Comment Manager by JustinZhengBC

Click the blue square in the toolbar to activate.

After pressing "done," the selected comments will be added to your clipboard.

Keyboard shortcuts:
---
Ctrl-Q (Ctrl-Z on macs): activate the extension
1-9: toggle comment
z/enter: done

Type {Option A|Option B} to make a drop-down box for variations on a comment. This feature is only recommended when the options are mutually exclusive.

Type \{Option A|Option B} to display {Option A|Option B} as text. The | that separates the options can be escaped similarly.

If the extension does not react, the local data might be corrupted. Try deleting all the comments.
