*** Cursor names.
|
|
|
88 |
|
|
|
89 |
Cursor resources require the name of the file in /usr/include/X11/bitmaps that
|
|
|
90 |
contains the cursor you want to use.
|
|
|

|
|

|
|
|
106 |
'no', or 'on' or 'off'.
|
|
|
107 |

|
108 |
** Wildcard matching.
|
|
|
109 |
|
|
|
110 |
The asterisk can be used as a wildcard, making it easy to write a single rule
|
|
|
111 |
that can be applied to many different applications or elements.
