Another option: with text selected, toggle column selection mode:
The default shortcut to toggle the mode is:
- Linux/Windows:
alt–shift–insert - Mac
cmd–shift–(numpad) *
(or Edit→Column Selection Mode)
It’s an inconvenient shortcut for Mac, as most laptops have no numpad. I remapped it to cmd–shift–8.
Column selection mode actually has other purposes too: it changes the default behavour when selecting text with the keyboard and mouse. Toggle it off again to return to normal selection behaviour.
