When I want to, for example, remove all "m2" from "### m2" in table rows (20+ rows of table), I have to slow down my clicking, because InDesign doesn't register a selection change (double click to select), if I do it too fast. Woud be good if it was instantaneous like Word.
My process: 1. Double click to select m2. 2. Press backspace or delete. 3. Double click to select next m2. And so on.

I know I could find-replace, but sometimes I don't want to set up a find and replace. And it just a little annoyance, which not only shows for tables, but also for text boxes if I remember correctly.
