+# ClearSelection
+
+*Since: nightly builds only*
+
+Clears the selection in the current pane.
+
+This example shows how to rebind `CTRL-C` to copy to the clipboard
+when there is a selection present (clearing it afterwards) or sending
+CTRL-C to the terminal when there is no selection:
+
+```lua
+local wezterm = require 'wezterm'
+
+return {
+  keys = {
+    {
+      key="c",
+      mods="CTRL",
+      action = wezterm.action_callback(function(window, pane)
+        local has_selection = window:get_selection_text_for_pane(pane) ~= ""
+        if has_selection then
+          window:perform_action(
+            wezterm.action{CopyTo="ClipboardAndPrimarySelection"},
+            pane)
+
+          window:perform_action("ClearSelection", pane)
+        else
+          window:perform_action(
+            wezterm.action{SendKey={key="c", mods="CTRL"}},
+            pane)
+        end
+      end)
+    }
+  }
+}
