interactive.singleKey:: In interactive commands, allow the user to provide one-letter input with a single key (i.e., without hitting enter). Currently this is used by the `--patch` mode of linkgit:git-add[1], linkgit:git-checkout[1], linkgit:git-restore[1], linkgit:git-commit[1], linkgit:git-reset[1], and linkgit:git-stash[1]. Note that this setting is silently ignored if portable keystroke input is not available; requires the Perl module Term::ReadKey. interactive.diffFilter:: When an interactive command (such as `git add --patch`) shows a colorized diff, git will pipe the diff through the shell command defined by this configuration variable. The command may mark up the diff further for human consumption, provided that it retains a one-to-one correspondence with the lines in the original diff. Defaults to disabled (no filtering).
