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.
Thanks for advice!
Sadly, all platfroms and all terminals don't include:
1) linux ttys (as in kubuntu 11.04 distro)
2) kde konsole terminal (unless configured to use xfree 4 input profile)
in both cases vim dont catch function keys with shift/control modifiers
Oh? Let me see what happens on openSUSE Linux 11.4...
In the Linux tty (e.g. /dev/tty4), Vim sees some Shift-Fn keys but not
others:
nothing Shift
F1 <Esc>[[A <Esc>[25~
F2 <Esc>[[B <Esc>[26~
F3 <Esc>[[C <Esc>[28~
F4 <Esc>[[D <Esc>[29~
F5 <Esc>[[E <Esc>[31~
F6 <Esc>[17~ <Esc>[32~
F7 <Esc>[18~ <Esc>[33~
F8 <Esc>[19~ <Esc>[34~
F9 <Esc>[20~
F10 <Esc>[21~
F11 <Esc>[23~
F12 <Esc>[24~
IOW it sees F1-F8 with or without Shift, F9-F12 only without. (Ctrl-Fn
is used there as synonymous of Ctrl-Alt-Fn, to switch virtual displays,
so Vim doesn't see them.). Now let's try konsole:
nothing Shift
F1 <Esc>OP
F2 <Esc>OQ <Esc>O2Q
F3 <Esc>OR <Esc>O2R
F4 <Esc>OS <Esc>O2S
F5 <Esc>[15~ <Esc>[15;2~
F6 <Esc>[17~ <Esc>[17;2~
F7 <Esc>[18~ <Esc>[18;2~
F8 <Esc>[19~ <Esc>[19;2~
F9 <Esc>[20~ <Esc>[20;2~
F10 <Esc>[21~ <Esc>[21;2~
F11 <Esc>[23~ <Esc>[23;2~
F12 <Esc>[24~ <Esc>[24;2~
Here Vim gets them all except Shift-F1; and by using Ctrl-K instead of
Ctrl-V as prefix I can see that it is correctly set up to identify them
too. What profile is my konsole configured to use? Hmm... "Default
(XFree4)".
Gvim, of course, sees them all (F1-F12 with or without Shift. OTOH,
Ctrl- and Alt-Fn seem to be snatched by the windowmanager). Well, that's
still 19 distinct keypresses that I can use in all the instances of Vim
or gvim that I use, and if someday I need more, I can use multikey
mappings. To see what you can use, some experimentation may be useful.
Best regards,
Tony.
