Using Shortkey is really when you want win some micro-times in very repetitive actions on some numerous objects!

It's not pleasant to use icons ? You know exactly that you make quietly...with maximum of efficacity!

You have all specifics addon pluggins on a special icone menu...and an icon is more visually memorizable than an abstract Ctrl + Shift + Z :)

With this menu I have 150 functions under hands with confort!

I use only K for subdivide, P for SSplit, B for Bridge, L for Loop selection, R for Rebuild :)
I can't memorized more!
