I've been using bash for years, and I still haven't come anywhere close to mastering the full range of available command line keyboard shortcuts. I've found the best way to get more under my fingers is to note a few on a Post-It stuck to the monitor, and then swap it for another one at intervals.
Here, are a few useful candidates.
(C = control key, M = alt/meta key.)
I learned some new shortcuts while researching this, so hopefully you learned something useful, too!
Ed Note: A quick note about the Perltidy tip from a fortnight ago. Thanks to Randal L. Schwartz for pointing out that it's a good idea to set up tests for your code, to check that it does the same thing after Perltidy is finished as it did before. As he discusses here, ultimately the only thing that can interpret Perl code entirely reliably is the Perl interpreter itself. So be aware that there are circumstances in which Perltidy (and similar programs) can break code!
