nice video by Dave Leeds.
surprisingly many people don’t know how to do it.
- move caret to next word with selection = ctrl shift right (⌥ ⬆ right)
- add selection for next occurrence = alt J (^ G)
- find next and move to next occurrence = F3 (⌘ G)
- put cursor = alt shift click
- Hold mouse middle(wheel) button and drag mouse
- When you are finding in the document you can click – select all occurences and it will spawn multicursor for all of them so you can edit. This is very powerfull with regexes!
