How to make the game easier in regards of mechanics?

Is there any collection of technics to make the game a little easier?

Some that I know of and which are used also in tournaments:

  • camera hotkeys

  • shift-blining stalkers or shift commands in general

  • mousewheel rapid-fire for warping in units and placing buildings

  • mousewheel rapid-fire for ghost snipes for HT feedbacks

  • some macro for queen injects

Anything else?

Or maybe some research about the “perfect” hotkey layout ?

Bump.
