.TH GRIDMENU 1 grid-0.0
.SH NAME
gridmenu \- grid window manager menu
.SH SYNOPSIS
.B gridmenu
.RB [ \-v ]
.RB [ \-t
.IR title ]
.SH DESCRIPTION
.SS Overview
.B gridmenu
is a generic, highly customizable, and efficient menu for the X Window System,
originally designed for
.BR grid (1).
It supports arbitrary, user defined menu contents.
.SS Options
.TP
.B \-v
prints version information to stdout, then exits.
.TP
.BI \-t " title"
displays
.I title
above the menu.
.SS Usage
.B gridmenu
reads a list of newline-separated items from stdin and creates a menu.
When the user selects an item or enters any text and presses Enter, his choice
is printed to stdout and
.B gridmenu
terminates.
.SS Keyboard Control 
.B gridmenu
is completely controlled by the keyboard.  The following keys are recognized:
.TP 2
Any printable character
appends the character to the text in the input field. This works as a filter:
only items containing this text will be displayed.
.TP 2
Left/Right (Control-p/Control-n)
select the previous/next item.
.TP 2
Tab (Control-i)
copy the selected item to the input field.
.TP 2
Enter (Control-j)
confirm selection and quit (print the selected item to stdout).
.TP 2
Shift-Enter (Shift-Control-j)
confirm selection and quit (print the text in the input field to stdout).
.TP 2
Escape (Control-[)
quit without selecting an item.
.TP 2
Backspace (Control-h)
remove enough characters from the input field to change its filtering effect.
.TP 2
Control-u
remove all characters from the input field.
.SS Exit codes
.B gridmenu
returns
.B 0
if Enter is pressed on termination,
.B 1
if Escape is pressed.

4	-	.SH SYNOPSIS
5	-	.B gridmenu
6	-	.RB [ \-v ]
7	-	.RB [ \-t
8	-	.IR title ]
9	-	.SH DESCRIPTION
10	-	.SS Overview
11	-	.B gridmenu
12	-	is a generic, highly customizable, and efficient menu for the X Window System,
13	-	originally designed for
14	-	.BR grid (1).
15	-	It supports arbitrary, user defined menu contents.
16	-	.SS Options
17	-	.TP
18	-	.B \-v
19	-	prints version information to stdout, then exits.
20	-	.TP
21	-	.BI \-t " title"
22	-	displays
23	-	.I title
24	-	above the menu.
25	-	.SS Usage
26	-	.B gridmenu
27	-	reads a list of newline-separated items from stdin and creates a menu.
28	-	When the user selects an item or enters any text and presses Enter, his choice
29	-	is printed to stdout and
30	-	.B gridmenu
31	-	terminates.
32	-	.SS Keyboard Control
33	-	.B gridmenu
34	-	is completely controlled by the keyboard. The following keys are recognized:
35	-	.TP 2
36	-	Any printable character
37	-	appends the character to the text in the input field. This works as a filter:
38	-	only items containing this text will be displayed.
39	-	.TP 2
40	-	Left/Right (Control-p/Control-n)
41	-	select the previous/next item.
42	-	.TP 2
43	-	Tab (Control-i)
44	-	copy the selected item to the input field.
45	-	.TP 2
46	-	Enter (Control-j)
47	-	confirm selection and quit (print the selected item to stdout).
48	-	.TP 2
49	-	Shift-Enter (Shift-Control-j)
50	-	confirm selection and quit (print the text in the input field to stdout).
51	-	.TP 2
52	-	Escape (Control-[)
53	-	quit without selecting an item.
54	-	.TP 2
55	-	Backspace (Control-h)
56	-	remove enough characters from the input field to change its filtering effect.
57	-	.TP 2
58	-	Control-u
59	-	remove all characters from the input field.
60	-	.SS Exit codes
61	-	.B gridmenu
62	-	returns
63	-	.B 0
64	-	if Enter is pressed on termination,
65	-	.B 1
66	-	if Escape is pressed.
