Posting a video won't help because the problem is not a "the wrong thing is happening" problem, but rather a "nothing is happening" problem. Posting a video of nothing happening seems silly, but then you Realize it is Revit so the sky is the limit on things not doing what you might expect them to.
So, you have some text, but you don't like what it says, so logically you want to change it. You double click on it and it opens the editing box. All of the text is highlighted. 25-years of using a computer has taught you that so far this is the normal behavior of a functioning text editor, and that if all the text is highlighted, you can just move your hand off your mouse and start typing with both hands and it will delete the bad text and replace it with your beautiful new ideas.
But Revit has other other plans for you.
You're looking at the sheet of paper on your desk, or the engineer's redlines as you type to make sure you carefully capture all of the important context. You reach back for your mouse to click ok... but then you realize that nothing has happened. The original text is still sitting there. Unaffected. Mocking you. Laughing at you.
So you hit Escape to start over - somehow thinking there was some mistake. Now Revit wants to know if you really want to save the changes to your text. Wait, what? What changes? You haven't changed anything. Frantically stabbing the Escape key does no good. It's as though someone has put a sticker on your screen that looks like an error message. You end up in a loop of rage clicking and escaping over and over again expecting logic to engage at some point and let you out of the hell that has become this editing session.
So you find your mouse again. You click No to indicate that you don't want to keep any of the changes that you didn't make. You double click the text again. Now you have to look back at your keyboard to find the backspace button... somewhere in the North 40 by the F12 and Prt Scr keys. God, finally, an empty text box. But now the mouse has moved the cursor a little ways away from it, so when you finally find where you were in your notes, and you've re-typed them your eyes swim back into focus on your screen to discover... yes, an empty text field. Again.
Fate has taught you the folly of the Escape key, and since you're a smart monkey you don't fall for that trap again.
You simply give in to the idea that Revit does not edit text. At all. It actually hates the idea. So you delete all of the text in your drawing and just make new, unique versions of each piece, never to bother with the fussy notion of trying to edit any of it, ever again.
