Now, when editing a {{Path|*.m}} file, you can type {{Key|K}} in normal mode and the word under the cursor will be searched for in the GNU Octave documentation index. Pressing {{Key|,}} yields the next occurrence. However, this does not work when using gVim, because gVim has only dumb terminal implemented. When using vim in some not dumb terminal, all works fine.

Unfortunately info does not work in dumb terminals. As gVim has only dumb terminal, a workaround must be done to access info. First select a terminal emulator, preferably fast loading one, as xterm, and install it. For installing it under Ubuntu, you can type:
 
$ sudo apt-get install xterm
 
Add the following line to your {{Path|~/.vimrc}} file:
 
autocmd FileType octave setlocal keywordprg=xterm\ -e\ info\ octave\ --vi-keys\ --index-search
 
Now you can type {{Key|K}} in normal mode and a new terminal window will opened and the word under the cursor will be searched for in the GNU Octave documentation index. You can set bigger font and specific window geometry of xterm by following line:
 
autocmd FileType octave setlocal keywordprg=xterm\ -fa\ 'DejaVu\ Sans\ Mono:style=Book'\ -fs\ 12\ -geometry\ 80x50\ -e\ info\ octave\ --vi-keys\ --index-search
