A thought about
Control-Space as the default key mapping for toggling Status=Complete ⇄ Active :
Not sure how typical this is for people who use LaunchBar and more than one human language or input method, but spacebar+metakey assignments are already a bit over-assigned on my system:
Ctrl-Spacebar → LaunchBar
⌥-Spacebar → Spotlight
⌘-Spacebar → Apple default for IME cycling
⌘⇧ -Spacebar → Apple default for Current ⇄ Previous IME
I’ll take a look now to see where I can change this in my local copy, but I wonder, more generally, whether others may already be overloading the spacebar with LaunchBar / Alfred, Spotlight and IME changing ?
PS am I right in thinking that ctrl + space is also an autocomplete menu default for code editing in Atom ?
