The following menuitems show all available color schemes, keymaps and compiler

Edit > Color Scheme ~

Edit > Keymap ~

Tools > Set Compiler ~

However, they can also take a bit of time to load, because they search all

related files from the directories in 'runtimepath'. Therefore they are

loaded lazily (by the |CursorHold| event), or you can also load them manually.

executed or after your .vimrc file is sourced. This means that the 'encoding'
