The main point of the G13 over G11/15 is the stick !
- You save at least 4 keys, since direction keys are not used anymore
- One finger (thumb) does all the steering, so 2 others become available for more pew-pew'ing

Steering with a cross-bar/stick is a little tricky, it is very hard to break the QZSD habit (yep, french keyboard ). But really, once it's done, there's no turning back.
