Just contributing a finding as I jump into CM6… I’ve been a Windows user for a long time (not sure if this is an OS specific issue). These two keymaps make the editor feel a lot better for me:
{ key: 'Ctrl-ArrowLeft', run: cursorGroupLeft },
{ key: 'Ctrl-ArrowRight', run: cursorGroupRight },
For me these have the effect of making Ctrl-Right and Ctrl-Left jump just 1 word. Hope it helps someone else!
