11/29/2016: I like Visual Studio Code a lot - it's got some warts, and gaps, but there's some thing's it does amazingly well (and some it sort of stumbles at). If you write in Powershell, it's probably the best/lightest/most-stable editor I've found, with the range of features you get, and rampant-growth and availability in user-created extensions - (Though it really needs better-rounded debugging... *grumble* ;P) .
one of my pet peeves for 'Code.exe' is it's lack of good quick popup
references for common tasks - well that and some of it's interface &
control choices that don't match most of the common keystrokes and
mouse behaviors I've gotten used to in other editors.
Autohotkey fills the gap!
Toward that end, the below is an Autohotkey-based quick-n-dirty Popup Cheatsheet for Visual Studio Code. If you use AHK & 'Code', you might find this gapfills a niche.
I don't doubt you can hack Code.exe itself to display a menu with a hot key binding. But I work for a living ; I don't want to burn a lot of time learning how to build objects in code.exe itself. :P But I do make tons of use of AutoHotKey these days -- (automation tied to working for a firm with a lot more user-interaction than I've had in the past: BOILERPLATE! AUTOMATE!) -- so I decided yesterday to take a few minutes and whip up a quick popup dialog in AHK that just lists out the key keyboard shortcuts I want to use (especially where addon extension commands and bindings are concerned).
It's pretty simple, docs are inline in the script (stored & kept updated at Github):
Two chunks below: the .ahk script file, and a .csv file that drives the displayed menu.
Lemme know if you have any questions. :^D
