Does OS X or Xcode have applications to manage cheat sheet/commands list?
Solution 1:
Try Dash.
Dash is an API Documentation Browser and Code Snippet Manager. Dash stores snippets of code and instantly searches offline documentation sets for 150+ APIs ... You can even generate your own docsets or request docsets to be included.
Solution 2:
I use CheatSheet which pops up a window if you press the Command key long enough and displays all currently available keyboard shortcuts.
Solution 3:
Perhaps the terminal command 'apropos' could be of use.
For example... 'apropos remote' should show commands for carrying out remote operations.
