My Mac keyboard got it's ~ character mapped incorrectly I had to reset the keyboard with
sudo mv /Library/Preferences/com.apple.keyboardtype.plist ~/tmp
Then restart my machine, to go through the keyboard re-initialisation. It then remapped the ~ AOK. Not sure why it got it wrong first time.
In vi -> i -> Ctrl+v -> key combo => vi prints raw code.
Install keycastr to see key presses on screen
Execute
brew cask install keycastr
To debug key presses into kitty terminal
kitty --debug-keyboard
To change Alfred to use local preferences, not synced one :
mv ~/Library/Application\ Support/Alfred/prefs.json ~/tmp/alfred-prefs.json
:profile start vim-performance.log
:profile file *
:profile func *
:profile stop
Look at the bottom of the log file for a sorted summary
Also generate a start-up time report with:
