Like I said I'm a screen guy so I'm used to ctrl+a and I got my keymap remapped so that caps lock is ctrl so ctrl and a are right next to each other b is in the middle of the keyboard and I find it irritating having to press ctrl and b.
Also I don't use ctrl+a but the home key so I'm missing nothing.
