During my use of kakoune I had been remapping x many times. Sometimes to X other times to <a-x>. But recently I came to conclusion that core x and X primitives are redundant. Having said that here is my final mapping I use every day:
map global normal v <a-x>
map global normal <a-v> <a-X>
# not necessary, remap v where do you like
map global normal q v
map global normal Q V
# map x and X to something useful
To select two or more lines with default bindings there is need to engage xX..
With my suggested mappings J..v or K..v, i.e. to select 3 lines down I would press JJv or 2Jv.
PS: all mappings are meant to be applied to qwerty layout.
I don’t use the view mode too, but I’ve utilized it for object selection since I find the default <a-i> and <a-a> cumbersome to use… and it sort of rings with Vim’s visual mode for me.
# repurpose visual mode keys for object selection
map global normal <a-v> 'v'
map global normal <a-V> 'V'
map global normal v '<a-i>'
map global normal V '<a-a>'
for x, i’ve just remapped it to do <a-x> instead.
