For text it's Recompose All Stories:
In Keyboard Shortcuts, it's in the section called Text and Tables if you want to give it a different keystroke.
If it's for something like a text variable or cross-reference, to get it to refresh, change your page view percentage.
Hi Steve Werner, nothing happens unfortunately, because of my Italian keyboard I think. Sorry for the late to answer anyway
It might be different because of your keyboard. Look in Edit > Keyboard Shortcuts > Text and Table. Set it to something else compatible with your keyboard.
