In Vim, I use Ctrl-T to indent, and Ctrl-D to deindent (in cases where automation doesn't handle it). Ctrl-T works with the correct indentation amount which is defined by the value of "shiftwidth"; whereas the Tab key inserts a tab, or spaces to get to the next tabstop if "expandtab" is in effect. I trained myself on Ctrl-T more than 20 years ago; some people remap the Tab key to indent.
