Alignment weirdness in the application timeline pane

Good afternoon,

I've got a weird one...

I was typing away this morning trying to give meaningful labels to objects on the slide and accidentally clicked a key combination on the keyboard (no idea what combination though) and now, when I rename objects in the timeline, the text is aligned to the right.

The back arrow on the keyboard sends the cursor to the end of the selected text instead of the beginning and vice versa.

Any ideas how I change it back? It's only happening on the project I'm working on.

Thank you

Karen
