hi,
if you do Alt+SPACE then any cursor movement would select, in
particular, most useful to me are Alt+U and Alt+O. But you probably
knew that?
Holding down SHIFT then press arrow keys also select as in common
editor behavior.
another way to select is press Alt+8, which select current word.
Pressing again should select larger semantic unit... for human
language texts such as English, it would be word, sentence, paragraph,
whole buffer. But this is not implemented yet.
emacs having lots of other commands. If we use Ctrl+key for selection,
that would take out a lot control key shortcut spots with I J K L and
U O, and it'd conflict with standard ones such as open, save, save as,
new, find, etc. (because we support both qwerty and dvorak)
