+# OSC 52 (terminal clipboard)
+
+If possible, setting the `clipboard` option to `terminal` will give
+best results because it will work over SSH and locally. However, there
+is limited support among terminal emulators for the terminal clipboard
+(which uses the OSC 52 protocol to communicate clipboard contents).
+Here is a list of terminal emulators and their status:
+
+* Kitty: supported, but only writing is enabled by default. To enable
+  reading, add `read-primary` and `read-clipboard` to the
+  `clipboard_control` option.
+
+* iTerm2: only copying (writing to clipboard) is supported. Must be enabled in
+  `Preferences->General-> Selection->Applications in terminal may access clipboard`.
+  You can use Command-v to paste.
+
+* `st`: supported.
+
+* `rxvt-unicode`: not natively supported, but there is a Perl extension
+   [here](http://anti.teamidiot.de/static/nei/*/Code/urxvt/).
+
+* `xterm`: supported, but disabled by default. It can be enabled by putting
+   the following in `.Xresources` or `.Xdefaults`:
+   `XTerm*disallowedWindowOps: 20,21,SetXprop`.
+
+* `gnome-terminal`: does not support OSC 52.
+
+**Summary:** If you want copy and paste to work over SSH, then you
+should set `clipboard` to `terminal`, and make sure your terminal
+supports OSC 52.
