Case statements becoming expressions in #swift 5.9 is a chance to up your multi-select game.

Keypresses (with Xcode Vim mode turned on):

ve to select the word “return”
cmd-opt-e held down to select all of them
x to delete them
kJ to move up a line and join the next line to it

sometimes I miss ^w from textmate that does the "select this word, then the next occurrence, and the next” operation in one easily repeated keypress. but it doesn't have Vim keybindings, so you win some you lose some
@airspeedswift also from textmate: cmd+opt+f to select all matching search. Also: cmd+| to filter through shell command. Basically the only two things I use it for anymore :/
@numist Xcode has select all matching search (and in selection only) but it doesn’t have a default keyboard shortcut for them.
