Searching Bookmarks and History

  • Add Bookmarks and History as separate “search engines”
    • Settings Manage Search Engines Add Search Engine
    • Give them a single-letter keyword each
    • Bookmarks: chrome://bookmarks/?#q=%s

    • On Mac: Cmd(splat) + L
    • Then enter the keyword (configured abnove - I’m using b for bookmarks and h for history) and hit Tab
    • Note that on Mac Catalina I’m finding that any search term you enter directly will get crappy results, so I just enter a random character and then tab inyo the actual search text box

Voting functionality

  • To add voting functionality to Trello, click the menu top right, then select powerups and search for the Voting powerup to add it.
  • Once it’s added you can vote on Trello cards by hovering over and pressing on the keyboard, or opening up the card and finding the Vote button on the right.
  • You can then order cards in a column by how many votes they have, by clicking the three dots at the top right of the column and selecting “Sort by…” then “votes”.

Other quick shortcuts

  • Copying / pasting cards between boards: Simply hover over a card and use Ctrl + C / Cmd + C, then go to the destination board and use Ctrl + V / Cmd + V. The key is to hover over either a card or a list (the strip at the top of the list). If you hover over a card, you could end up copying a card into a card instead of into a list.
  • Adding your name to a card: Hover over it and press the spacebar (doesn’t work if the new card bit at the bottom has focus).

File Explorer breaks / changes appearance after Windows 10 update.

Avoiding an automatic update to Windows 11

This article is good for all the different ways you can evade the auto-install - basically you can fiddle about with the registry so that you continue to get updates vut don’t get windows 11, or you can pause updates. …although it turns out I have nothing to worry about because my PC doesn’t meet the min requirements needed for win 11.

Avoid having your large image take over the whole of Miro

You know that thing when someone asks you to add your photo to Miro, and suddenly your face has taken over the whole of space and time while everyone stares up your left nostril?

Well, thanks to the Miro forum I have two solutions - one for facilitators and one for participants.

Facilitators: Upload small images in advance. Ask people to click an image and select the Replace Image icon on the little toolbar that pops up above the image.

Participants (assuming your facilitator didn’t know the tip above): Keep a small image handy, like one of these (I keep them in the root of my Events folder)…



Drag your small image onto the board. Then click it and select the Replace Image icon on the little toolbar that pops up above it.

That’s it! Happy Miroing.

Reinstate Alt + Enter Resharper keyboard shortcut in Visual Studio

  • Alt + Enter stopped working for me after I changed the default keyboard mapping scheme
  • The solution:
    • Extensions => Resharper => Options
    • Keyboard => Shortcut Scheme
    • Change keyboard scheme (I changed to Visual Studio from IntelliJIDEA, not sure if it would have worked if I was changing in the other direction)
    • Click Apply Scheme
    • Do something that would warrant a refactor - eg change the name of a variable
    • Place your cursor on the renamed var
    • Hit Alt + Enter
    • You should get a popup which will allow you to choose to override the VS default shortcut with the new Resharper action.

  • Search terms: record screen / screen recording

Record your screen in Windows 10

Use Vimeo

  • My preferred option
  • Can be done in the browser
  • Go to Vimeo website
  • Set yourself up with a free account
  • Big blue button - “New video” - “Record screen”
    • To stop recording, find the little bar on same screen as browser, will probably be floating bottom left
  • Context menus are recorded
    • NB if using VS + Resharper it’s a good idea to use Ctrl + Shift + R then select option from menu, instead of using direct shortcuts like Ctrl + R + M.
    • The reason is that the viewer gets better visual feedback on which option you’re using.
  • To download:
    • Go to list of all videos, click “Send file” - you will get a download screen
  • To play back double speed:
    • In browser: Click Settings cog, bottom right of video, select Speed
    • As file:
      • Download (see above)
      • Open in Windows Media Player
      • Right-click and choose Enhancements => Play speed settings
  • If using Resharper menus it’s a good idea to use Ctrl + Shift + R to see which option you’re selecting, instead of direct shortcuts like Ctrl + R, M

Use OBS Studio

  • Free, open source
  • Has to be downloaded
  • Download from here
  • Context menus are recorded (I think)
    • NB if using VS + Resharper it’s a good idea to use Ctrl + Shift + R then select option from menu, instead of using direct shortcuts like Ctrl + R + M.
    • The reason is that the viewer gets better visual feedback on which option you’re using.

Use Game Bar

!!! Not recommended for coding demos, because context menus are not recorded - so if you want to demo using Resharper tools, for instance, you never see the Resharper menu pop up on screen.

  • Open the app you want to record.
  • Press the Windows key + G at the same time to open the Game Bar dialog.
  • Check the “Yes, this is a game” checkbox to load the Game Bar. …
  • Click on the Start Recording button (or Win + Alt + R) to begin capturing video
  • To find the resulting file:
    • Press Windows + G again
    • Select the recording in the gallery
    • Click Open file location (lower down on the right).
  • To play back double speed:
    • Open in Windows Media Player
    • Right-click and choose Enhancements => Play speed settings
  • See here for useful cheat sheet to use in workshops

Record your screen on a Mac

  • Open QuickTime Player
    • Note that this opens the Finder app as its first screen, which can be confusing and feel like it hasn’t open at all.
    • But you will now have the QuickTime menu visible at the top of your screen, with all the quickTime functionality.
  • Choose File > New Screen Recording
    • You will now have a dotted line around your screen which you can drag to adjust the screen area you want to record
    • Once you’re happy, just click the Record button on the menu bar.
  • If you want to record sound too (by default it will be silent):
    • Click on the Options down arrow next to the Record button
    • Select your internal microphone
  • Context menus are recorded
    • NB if using Rider + Resharper it’s a good idea to use Ctrl + Shift + R then select option from menu, instead of using direct shortcuts like Ctrl + R + M.
    • The reason is that the viewer gets better visual feedback on which option you’re using.
  • How to stop recording!
    • This is not obvious at all.
    • In your menu bar will be a tiny Stop icon (a grey square). Click this.
  • How to play it back!
    • Also can be not obvious, as if you’ve recorded full screen it will just feel like you’re looking at your screen. And if you happened to start by looking at some form of media player, you might get confused.
    • When you hover over your screen, a play bar will appear. Click play to start playback.
    • The play bar will remain visible while you playback, unless you move your cursor to the edge of the screen. Move your cursor back to the centre to see it again. To stop playback, just click Pause.
    • Then you can use the QuickTime menu to work with your recording.
    • To play back double-speed:
      • While watching a video in QuickTime:
        • Hold the option key.
        • Click the fast forward button.
        • For each click of the fast forward button, you’ll see the speed start to increase in 0.1 increments from 1.0x → 1.1x → 1.2x → etc. all the way up to 2. - 0x.
      • There is a bug though… The audio drops once you hit 2x speed.
        • To work around this bug, simply move to 1.9x speed and stop.
  • How to find it!
    • By default, the recording will be in your desktop.
    • To find it, use File => Move
  • See here for useful cheat sheet to use in workshops

Change your DNS server / fix problems where some sites are suddenly unavailable

  • Update: The issue appeared to fix itself after a couple of hours. No idea how / why.
  • I tried this because I couldn’t access Twitter or LinkedIn on my Windows laptop
  • When I use Edge or incognito, I get a Twitter error. Not the same as the one I originally got (when I got all the context menus and surorunding Twitter site stuff, but errors instead of actual content), just a blanket “Try again” with a little Twitter logo. When I use Chrome non-incognito, I just get “This site can’t be reached” - which has changed since earlier.
    • When I ran network diagnostics, it suggested there was a problem with my DNS server: “Windows can’t find the host name “” using DNS.”
      • So I changed Windows to use same DNS server as Macbook (, with Google - - as secondary server), but it didn’t work
    • My MacBook didn’t have the same problem
    • Other things that didn’t fix it:
      • Switching to a different Chrome profile
      • Restarting windows laptop
      • Temporarily turning off Avast Firewall
      • Secure browsing
      • Temporarily turning off Avast Web Shield (Protection => Core Shields)
      • Trying a different browser (Edge)
      • Switching to WiFi instead of ethernet cable
      • Flushed browser cache using Ctrl + Shift + Delete (claresudbery gmail profile)
      • Flushed DNS resolver cache in Windows Terminal: ipconfig /flushdns
      • Check whether is blocked in C:\Windows\System32\drivers\etc\hosts (it isn’t)
      • Look up using nslookup in Windows Terminal - weirdly this comes back with an IP address, so I don’t know why network diagnostics says ‘Windows can’t find the host name “” using DNS.’
