Note that you can enable ProTools shortcuts in other software, for example to enable them in Audition the instructions are here. Reaper instructions are here.
There is nothing better to speed up your editing, or impress your clients, like knowing shortcuts for all your most needed tasks. Protools contains hundreds of keyboard shortcuts, my favourite ones are here:

Command + H – heal a split.
Command + Shift + I – Import Audio.

Command + Option + Command – return all waveforms to normal size.
Command + down arrow – make tracks smaller.
Command + Option + up arrow – make all tracks bigger.
Command + Option + down arrow – make all tracks smaller.
Command + M – Mute region.

New Feature: useful for finding the sync clap:
Imagine you have a sound file with dozens of whooshes. Each of them has five seconds of space in between. Jump from one whoosh to the next by pressing tab via the “tab to transient” function. You can turn tab to transient on and off by clicking an icon in the edit window header. Type command-option-tab to save reaching for the mouse every time.
