How do you change color schemes and work with tabs in VIM?

:colorscheme name switches the color theme; :tabedit file opens another file in a new tab.

Both commands lean on Tab-completion in Command mode: type the start and press Tab to cycle through valid values (scheme names, then file paths). That's a general vim habit worth forming — most : commands autocomplete their arguments.

Color schemes and tabs:

Changing color scheme:

:colorscheme desert

Use Tab to cycle through available schemes like: blue, darkblue, default, delek, desert, elflord, evening, industry, koehler...

Working with tabs:

:tabedit Documents/

Use Tab to autocomplete file/directory names.

Tip: Tabs appear at the top of the VIM window, showing multiple open files.
