Highlights Cursor and lCursor are documented under :help 'guicursor'.
Highlight CursorIM is documented under :help CursorIM
- Cursor is the cursor color whenever it is obeying neither lCursor nor
CursorIM, or when it would, except that they haven't been set.
- lCursor is the GUI cursor color when a keymap is acrive ('iminsert' is
set to 1). IIUC, it cannot be used in non-Dos/Windows Console mode,
because in that case 'guicursor' is not used, t_SI and t_EI are used
instead, and they make no provision for using keymaps.
- CursorIM is the cursor color when an Input Method (XIM or IME) is
active ('iminsert' is set to 2).
Like all highlight groups, all three settings are global: if you are
using different keymaps in different split-windows, and each of them
sets lCursor to a different value, the last one set wins out and applies
to _all_ keymaps you might be using in parallel ('keymap' and 'iminsert'
are buffer-local options).
