" notes for movements and usage : ------------------------------------------------- {{{
"" the general strategy is to choose invalid commands
"" (e.g. operation1+operation2 or operation1+non-movement)
"" and commands that don't doo anything (e.g. up+down)
"" E.g. cl is the same as s
"" 'escape keys are lame'
"" good combinations giving movements already in better combinations
"" are also registered. Ideally, any of such movements
"" should perform something or echo 'Non used combination'.
"" I should make <nowait> option work for this to be really useful.
"" and to try to keep navigation inside keyboard. E.g.:
"" sdfghjkl toolkit ****
" -->  H, L, <space>, <cr>, and <bs> do things that you almost never need
" --> show buffers of clipboard and search
" :echo @" . @/
