Reply To: Proportional scaling shortcuts disappeared (?)

I’m having trouble recreating this, but it does sound weird.

Normally if you have the black arrow selected, shift+drag one corner of a text box = proportionally scale the text box, but don’t resize the text. Ctrl+drag = stretch the box non-proportionally, and stretch the text too. And ctrl+shift = proportionally scale box + resize text to match.

You’re saying none of these three options does anything when you drag the corner of a text box? Does the corner still move?
Is it definitely a normal text box you’re trying to stretch?
Do you have the black arrow selected or white arrow or maybe the scale tool (E) selected?

If it’s indeed related to settings, the usual fix is to delete your preferences and let indesign re-create them. Here are the instructions – https://forums.adobe.com/thread/526990
