Is there a way to get a list of all installed color schemes in Vim? That would make very easy to select one without looking at the .vim directory.
.vim
You can see the list of color schemes under /usr/share/vim/vimNN/colors (with NN being the version, e.g. vim74 for vim 7.4).
/usr/share/vim/vimNN/colors
NN
vim74
This is explained here.
On the linux servers I use via ssh, TAB prints ^I and CTRLd prints ^D.
^I
^D
