Menu Items

• Each menu consists of items followed by a key shortcut shown in brackets.
• If the menu is too large to fit on the terminal, it is not displayed.
• Pressing the key shortcut chooses the corresponding item.

Examples:

"Kill" X kill-pane 
"Respawn" R "respawn-pane -k" 

• "Kill" X kill-pane
  • "Kill" is the text shown for the menu item.
  • X is the key shortcut.
  • kill-pane is the command to run when the item is selected.
• "Respawn" R "respawn-pane -k"
  • "Respawn" is the text shown for the menu item.
  • R is the key shortcut.
  • "respawn-pane -k" is the command to run when the item is selected.

Conditional Menu Items

You can set conditions for menu items.
Items that don't match the condition can be disabled.

• Follows a structure: "${?#{conditional},,-}Display Text" x "command" E.g.,:

  "#{?#{>:#{window_panes},1},,-}Swap Up" u "swap-pane -U"
  

• The conditional: {>:#{window_panes},1} checks #{window_panes} to see if there's more than one pane in the window.

• That's passed to the outer conditional format (#{?conditional,true,false}), where true is set to nothing, and false is set to -.

  • If there is more than one pane, do nothing.
  • If there isn't more than 1 pane, disable (set to -)
