Copy Source

Cause: tmux runs with the mouse on, so the wheel can scroll its history. That also routes a plain drag into tmux copy-mode, which copies over OSC 52 and leaves copy-mode on release, dropping the highlight at once. You couldn't tell anything was copied. Only Shift+drag gave a browser selection.

Fix:

  • A left-button drag in the pane becomes a browser selection (what Shift+drag does). It stays highlighted and is copied on release, with a short "Copied N characters" toast. Double-click (word) and triple-click (line) work too.
  • Ctrl+C copies the selection when there is one, and interrupts only when nothing is selected.
  • The mouse wheel still scrolls tmux history, and clicks on the tmux status line (window tabs) still go to tmux.
  • The footer hint reads "drag copy", and the key help lists Drag and Ctrl+C.
