What program, application, or shortcut have you never been able to get behind, even though most people tout up as the best thing for developing? It could be either because you don't care to learn/use it, or because you always forget how to use it.
For me, its
tmux. I realized it today when I kept complaining about my
ssh session crashing and having to start again. My teammate reminded me that
tmux has persistent sessions, but after 3 or 4 times of trying to use it more often, I just find it frustrating and never really use it. Maybe one day I'll actually get good at using it, but for now it just seems like a lot of trouble and time that will slow me down in the short term.
Some other honorable mentions:
emacs: I know the basics of
vim, but holy heck am I slow at making changes
curl: I basically need to relearn
curlevery time I want to make a simple request from the command line
