There is absolutely nothing I do in an IDE frequently enough to memorize a bunch of arcane commands, especially in 3 days. Regex solves any mass-operations. For everything else the bottleneck is how long it takes to reason about code, not how quickly I can manipulate it.
I will say that if I keep getting jobs where I have to use an IDE on a remote VM on AWS, I might prefer SSH/Vim to that bullshit. The frequency with which IntelliJ locks up all four of those virtual hamster wheel powered CPUs requiring a full restart is basically daily and sometimes multiple times a day.
