Highlight text + Backspace/Delete does not delete text in AI chat

[JBroadway]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

A few days ago, I updated Cursor and noticed in AI chat, I can no longer highlight text and press backspace to delete. Now the only way I can delete text in AI chat is one word at a time with CTRL + Backspace

Strange enough, Ctrl+A then Backspace or Delete works.
But if you try to type > then make a selection > delete or backspace > this doesn’t work for me.

Steps to Reproduce

To reproduce, start typing text in a new chat, highlight text and press backspace and text is not deleted. Cursor will delete one character.

Expected Behavior

Highlighted text should delete on backspace or delete

Operating System

Windows 10/11

Cursor IDE Describe the Bug This didn’t used to happen, and I’ve been hesitant to report it because I’m sure it’s so annoying someone else was going to do it, but that doesn’t appear to be the case. When I am typing in the prompt window to the AI Agent, if I use my standard shift + Home to select all the text and then hit Backspace, nothing happens. I have to use DEL, and even then it deletes all of the text except the first and last characters. S…

Does this stop you from using Cursor

No - Cursor works, but with this issue

Thanks for the report! I’m having trouble reproducing this on my end. To help debug:

Could you please test:

1. Launch Cursor in safe mode (no extensions): cursor --disable-extensions in terminal

2. Does it happen in a new/empty workspace?

3. Exactly how are you selecting text? (mouse drag, shift+arrows, or another method?)

4. Does this happen always or intermittently?

If still happening, could you share:

• A screen recording showing the issue

• Whether you have any custom keyboard software or keybindings

Pay attention to your bug posts, this has been an issue for months - my topic was automatically closed and contains a video of the bug happening:

Shift + home highlight, then backspace does not delete text in AI prompt window

Shift + Home is not working yet, but the team is working on a fix.

I use cursor on a remotely hosted (it’s a physical machine in my office) Fedora install, and this shift+home bug has been present for forever.

There is also a bug (that has also been present for forever) where when you first start Cursor you can’t type anything in the chat window until you create a new window and then swap back to the old one.

These bugs exist in both 1.0 and 2.0 so please don’t just say “try the new version” - 2.0 is actually worse because it refuses to respect the re-size of the chat window and constantly changes it with each new line printed.

Honestly the UI for this program is a comedy of errors and I would be laughing had I not spent over $1,000 on using it so far.
