[vox-tech] vim question

[Peter Jay Salzman]

ok, here's a non-ugly(?) answer:

this is the last 3 lines of the file:

-> :!top
-> :!nice -n10 planetary % &
-> :w

the goal is to execuate the instructions with <F9>, <F10> and <F12>.

this will execute the last line:

map <F1> mzG"zyy:let @z=strpart(@z,3)<CR>`z@z<CR>

here's the parse:

mz    place the z marker (no relation to the z register) at the current
      cursor position.  this is so the cursor returns to this location
      after executing the marker.

G     go to the end of the file

"zyy  yank the last line of text, "-> :w" into the z register

:let @z=strpart(@z,3)   forms a substring of register z consisting of
      the 4th through last character.  assigns it to register z.  the
      colon is part of the let command.

@z    execute the contents of register z


the more i learn about vim, the more i realize how little i know...
