 .SH NAME
 Tdrop - make dropdown terminals and windows
 .SH SYNOPSIS
-tdrop [\fIOPTIONS\fR] [program name or cmd]
+tdrop [\fIOPTIONS\fR] [program name or cmd] [program options ...]
 .SH DESCRIPTION
 	Tdrop is used for hiding/unhiding programs to acheive quake/dropdown functionality. It can create a dropdown window if one does not already exist or turn the current window into a dropdown on the fly. It provides options to control the intial size and position of dropdowns, for example to leave panels visible or to deal with window borders. When used with a terminal, it provides an option to specify the name of a tmux session to automatically start. It also allows the user to specify arbitrary options/flags to be used when starting programs. It uses window IDs as opposed to classes, so it can be used with multiple windows of the same program.
 
 	It also has the ability to automatically hide and automatically show dropdowns. For example, it can be used to automatically hide a terminal when opening something from it, e.g. an image viewer, video player, etc. Tdrop can         then automatically bring back the terminal whenever the image view, video player, etc. is closed. See the Examples section for more information.
 .SH Commands
-Tdrop expects the name of a program or 'current' (to use the current window) as the last argument to create a dropdown (optionally followed by any flags to that program). Alternatively, it can take one of auto_show, auto_hide, or toggle_auto_hide. Neither functionality is particularly useful called directly from the command line; the former should be bound to a key, and the latter is better used in shell functions/aliases or with a file opener (e.g. in the rifle.conf).
