Hello,
I've written a math keymap and menu plugin

P.S. after installing the vimball and starting to read the helpfile:
1):help mathmenu.txt gives an error, E21 (Cannot make changes,
'modifiable' is off), because its modeline contains :fenc=utf-8: which
would (temporarily) set 'modified'. The display is correct but I have
enc=utf-8 fencs=ucs-bom,utf-8,latin1 so the file would be treated as
UTF-8 even without the modeline. (Note that this modeline changes
'fileencoding' _after_ the file has been read, which is too late if it
has been read wrong by virtue of 'encoding' and/or 'fileencodings'.)
Hmm, I've taken the encoding modeline stuff off my
http://mysite.verizon.net/astronaut/vim/index.html#MATH versions ; I
guess you got a copy via vim.sf.net -- so I should update that one soon.
2) On the two lines containing the "grouping symbols" B< and B> (lines
158 and 159 of the helpfile), the second column is displayed
erratically in konsole (with Andale Mono 8) but not in gvim (with
Bitstream Ver(a Sans Mono 8): moving the cursor vertically over these
lines shifts their second parts left or right by one character cell
depending on the cursor column. According to
http://www.unicode.org/charts/PDF/U2300.pdf the codepoints U+2329 and
U+232A are "deprecated for mathematical use" (in favour of U+27E8 and
U+27E9 IIUC) "because of their canonical equivalence to CJK
punctuation". (Indeed, in gvim 7.2.385 with GTK2/Gnome2 GUI, these two
symbols are shown as "wide CJK" glyphs: when the cursor is on them its
width doubles.)
OK -- if you snoop through the keymap/math.vim file you'll see that I've
got commented-out versions of B< and B> using those two codepoints --
well, v3g has commented out versions. I'll go ahead and put v3 up on
vim.sf.net shortly.
Thank you,
Chip Campbell
