Hello!
Since long ago using this config:
noremap .<esc>:tnext<cr>
noremap ,<esc>:tprevious<cr>
Now I missing (.) dot command to repeat last action. First I've tried
to remap them to Ctrl+. but with no success. It seems it must be done
some other way than:
noremap<C-.> <esc>:tnext<cr>
noremap<C-,> <esc>:tprevious<cr>
Two questions:
1) Can Ctrl+. be mapped and how?
2) What's your favorite mappings for tnext/tprev?
1) The only Ctrl+printable keys which Vim can reliably see are the
following:
Ctrl+@ = 0x00
Ctrl+A to Ctrl+Z = 0x01 to 0x1A
Ctrl+[ = 0x1B = <Esc>
Ctrl+\ = 0x1C
Ctrl+] = 0x1D
Ctrl+^ = 0x1E
Ctrl+_ = 0x1F
Ctrl+? = 0x7F
Ctrl+a to Ctrl+z = same as Ctrl+uppercase
However, most of them are already bound to something useful.
Ctrl+_non_-printable keys may or may not get passed to Vim depending on
your OS, your keyboard interface, and, for Console Vim, the specific
terminal you're running in. You may have to experiment with the help of
the Ctrl-V (or Ctrl-Q) prefix in Insert mode, see ":help i_CTRL-V",
":help i_CTRL-Q" and ":help Ctrl-V-alternative".
2) My favourite keys to assign to the {lhs} of _any_ mapping are <F2> to
<F12> (with the exception of <F10> if it is used to trigger the System
menu), and <S-F1> to <S-F12>. If you don't have enough with those 22
keys, use a few of them as prefixes for longer {lhs}es for mappings
which you won't need too often. AFAIK those F keys (other than unshifted
F1 = Help and sometimes unshifted F10 = Menu) aren't used for anything
else, and, when used with no modifier or with only Shift, they are
reliably passed to Vim on all platforms and all terminals.
Specifically for :tabnext and :tabprev, however, you might take
advantage of the fact that Ctrl+PgDn and Ctrl+PgUp have the same
function, in both Normal and Insert mode, see
:help :tabnext
:help :tabprevious
and notice that the tag anchors on the right hand apply to Ctrl-PageUp
and Ctrl-PageDown in both Normal and Insert mode.
On most "desktop-type" keyboards the PageUp and PageDown keys can quite
easily be depressed with the right index finger while holding the right
Ctrl key down with the right thumb. Unless of course (like some Vim
users :-P if I may believe some of the comments I've seen) you use (real
or virtual) manacles to prevent your wrists from moving away from the
SDF JKL "home position" when typing.
Laptop keyboards may vary in this respect.
Best regards,
Tony.
