Remap your keyboard in X!  Ok, so not really a tool, but one of those
things you wish someone had told you about earlier.  Excellent for
getting easy access to all those neat [unicode][unicode]
[[symbols|unicode_sampler]] (generated with [[gen_sampler.py]]).

You're welcome to my [[~/.Xmodmap|_Xmodmap]] file, which I version
with [[dotfiles]] so it stays up to date across several computers.

[gucharmap][] is a nice tool for finding Unicode encodings for
whichever character you're looking for.

Another approach to binding special characters is to use the
[[compose_key]].  For example, I use Xmodmap for Greek letters, and
XCompose for accented characters.
