Description

This is an intermittent issue, it seems to behave differently based on where in the text input area the cursor is located and whether you've previously deleted text using backspace or not.

For context: on macOS alt+right moves is a system-wide shortcut to move forward a word. This works correctly inside opencode most of the time, but for some inputs it will move word-wise while you're in the beginning of the text area, but after crossing some mysterious threshold pressing it again will suddenly cause it jump to the end of the line, skipping many words along the way.

It's tricky to reproduce intentionally, but common enough in daily use to be mildly infuriating. The steps below reliably reproduce the issue

OpenCode version

1.0.134

Steps to reproduce

  1. Start a new opencode session
  2. Type or paste reproducing this is surprisingly tricky. seems to have to do with deletion.
  3. Use alt+left to move the cursor to the . right after the word "tricky"
  4. Use backspace to delete the word tricky.
  5. Re-type "tricky."
  6. Hit alt+left a few times to move the cursor to the beginning of "surprisingly"
  7. hit alt+right a few times and after passing the word "tricky" the cursor will jump to the end of the line instead of continuing to move word-wise

This issue might be a duplicate of existing issues. Please check:

  • #4261: Option+Right not jumping words as intended in some scenarios

Both issues describe similar behavior with macOS alt+right/option+right jumping to the end of the line instead of moving word-by-word. Feel free to ignore if there are specific differences in your case.

For keybind-related issues, please also check our pinned keybinds documentation: #4997

Update: the reproduction steps are different, but this seems to be the same underlying bug as https://github.com/sst/opencode/issues/4261. I opened a PR on opentui which has fixed the issue for me https://github.com/sst/opentui/pull/394
