Do not break the flow

They told you

"Do not use your mouse if you want to be productive"

"efficient, painless, mouse-free development is possible"

- Jared Carroll (ruby)

"Navigate a menu with [the] mouse interrupts the flow."

Skyrocketing shortcuts

Bad

What happened to keyboard

Should not happen to shortcuts

Well balanced modifiers

Exercice

Save : Ctrl + s

Print : Ctrl + p

Cut : Ctrl + x

Quit : Ctrl + q

Ease of use matters

source : caewatch.com

Number of shortcuts

Eclipse : ~ 200

Webstorm : ~220

SublimeText : ~250

But wait !

Shift -> already binded

Ctrl -> already binded

Alt -> already binded

Super -> already binded

Good, then

source : darkvision hardware

Keyboard WTF 1

too long shortcuts

examples :

super, k, super, b

alt, t, o, a, alt+k, spacebar, enter

Keyboard WTF 2

grey shortcuts

Rename : shift+ f6 ?

delete : ctrl + shift + k ?

delete : ctrl + y ?

Good shortcut

Easy to memorize with hand

Optional : easy to memorize with brain

Easier if fallback (abbreviation, context menu, cheat sheet)

Principle of least surprise applied

Extensions are logical

Frequency and ease of use are proportional

... but try to understand native shortcuts before to customize

Exercice 7

Try to define easy access to shortcuts following the preceding rules
