[BUG] ctrl+o to expand doesn't expand Read #8214
Description
Preflight Checklist
- I have searched existing issues and this hasn't been reported yet
- This is a single bug report (please file separate reports for different bugs)
- I am using the latest version of Claude Code
What's Wrong?
The Read tool has a description that says (ctrl+o to expand), but pressing ctrl and o does not expand the text.
What Should Happen?
Either the incorrect (ctrl+o to expand) text should be removed, or it should be expanded in the transcript view.
Error Messages/Logs
n/aSteps to Reproduce
- Tell Claude to read a file with the Read() tool
- Claude Code interface says ctrl+o will "expand" the lines
- User presses ctrl+o to toggle detailed transcript
- The lines remain collapsed.
This should be easy to reproduce. This is my exact reproduction:
> Please read my_file
● Read(my_file)
⎿ Read 31 lines (ctrl+o to expand)
● The file contains 30 lines with the repeated text "this content goes for 30 lines" followed by an empty line 31.
> /status
Claude Code v1.0.123
Notice that it tells me I can see the content by pressing ctrl+o.
After pressing control and o, it goes to the detailed transcript view:
> Please read my_file
● Read(file_path: "/home/xerool/my_project/my_file")
⎿ Read 31 lines (ctrl+o to expand)
● The file contains 30 lines with the repeated text "this content goes for 30 lines" followed by an empty line 31. 11:20 PM claude-sonnet-4-20250514
Notice the bug: detailed transcript didn't expand the lines. It still says (ctrl+o to expand) even though I'm already in the expanded view.

Is this a regression?

It would be great to get it fixed--it is currently not possible to inspect the commands and outputs for those, which is pretty important if you want to follow what is being done.

I think this is now "fixed" as of one of the newer versions. It still doesn't expand in the transcript view, but there's no more misleading "(ctrl+o to expand)" text promising an expansion
