+# Get Mouse Copy/Paste Working In Kitty
+
+With tmux's mouse mode enabled (`set-option -g -q mouse on`), you can use the
+mouse to make a drag selection of some text. You can then paste it within a
+tmux session using `Cmd+v`.
+
+If you are using tmux within the [Kitty terminal
+emulator](https://sw.kovidgoyal.net/kitty/), you'll get more text pasted than
+you bargained for. Kitty's clipboard _appends_ by default. So after several
+selections have made there way into tmux's buffer history, a paste will result
+in all of those buffers values being appended together and output to the
+terminal.
+
+To fix this, you need to change Kitty's clipboard to be `no-append`.
+
+```
+# ~/.config/kitty/kitty.conf
+clipboard_control write-clipboard write-primary no-append
+```
