set status_hold [<text>]
This variable sets the string displayed in the status bar when the current window has HOLD_MODE turned on, and there are lines of text waiting in the queue to be displayed.
This string is represented by %H in the STATUS_FORMAT string. The %H is treated literally within STATUS_HOLD.
Customizing the message indicating lines are being held:
/set status_hold Held Lines:
When lines are held, both this setting and STATUS_HOLD_LINES are activated.
