+To launch a program with its override, select its name in this list, then Tab
+to **Copy alias to clipboard** and press Enter. This copies a Bash alias into
+Fenrir's clipboard without selecting the override or closing the menu. Paste it
+into your Bash configuration, such as `~/.bashrc`, and load that configuration
+in a new shell. The aliases use the executable names `cninjam`, `nmtui`, `rogue`,
+and `codex`; Default has no alias. Existing aliases with those names are replaced
+when you load the definition.

+The alias requests the override through `socat`, then launches the real program
+with the arguments you supplied. Errors remain visible, and the program still
+launches if the request fails, remote control is disabled, or Fenrir or `socat`
+is missing. Socket inactivity is limited to two seconds. It uses the standard
+socket, or your configured `remote.socket_file`, rather than a process-specific
+socket that changes at restart. Paste with Fenrir's clipboard command; desktop
+clipboard synchronization follows your normal clipboard settings.
