APPENDIX 3
POINTER DEVICE SUPPORT IN THE

This appendix describes the default behaviour of supported pointer devices when running THE; usually a mouse.

SYNTAX:

Mouse "keys" have the following syntax:

[a-]bcB IN window	Description
[a-]	is a keyboard modifier, the same as keyboard keys. The 'a' can be one of S,C or A for SHIFT, CONTROL and ALT respectively. The '-' is mandatory.
b	is the mouse action. This can be one of P, R, 2 or D for PRESS, RELEASE, DOUBLE_CLICK and DRAG respectively.
c	is the mouse button. This can be one of L, R or M for LEFT, RIGHT and MIDDLE respectively.
B	stands for BUTTON
IN	is mandatory keyword
window	is the area of the screen in which the mouse event is to take place. The valid values for this are: Filearea, Cmdline, Idline, Arrow, PRefix, STatarea and Divider

EXAMPLES:

Mouse Event	Description
S-PLB IN PR	Left mouse button is pressed, while holding down the SHIFT key, and the mouse positioned in the prefix area.
2RB IN I	Right mouse button double-clicked in idline.

DEFAULTS:

Mouse Event	Command(s)
PLB in FILEAREA	cursor MOUSE
S-PLB in FILEAREA	cursor MOUSE#reset BLOCK#mark LINE
C-PLB in FILEAREA	cursor MOUSE#reset BLOCK#mark BOX
S-PRB in FILEAREA	cursor MOUSE#mark LINE
C-PRB in FILEAREA	cursor MOUSE#mark BOX
PRB in FILEAREA	cursor MOUSE#sos MAKECURR
S-DLB in FILEAREA	cursor MOUSE#mark LINE
C-DLB in FILEAREA	cursor MOUSE#mark BOX
2LB in FILEAREA	cursor MOUSE#sos EDIT
PLB in PREFIX	cursor MOUSE
PRB in PREFIX	cursor MOUSE#sos MAKECURR
2LB in PREFIX	cursor MOUSE#sos EDIT
PLB in CMDLINE	cursor MOUSE
PLB in STATAREA	status
PLB in IDLINE	xedit
PRB in IDLINE	xedit -
PLB in DIVIDER	screen 1

NOTES:

1. In the X11 port, pressing the middle mouse button anywhere within the THE window, will result in the contents of the X selection being pasted where the text cursor is currently displayed. If you hold down any modifier key, such as SHIFT or CONTROL, that sequence is passed to THE and can be mapped. Therefore; PMB or RMD is NOT able to be used in THE, but C-PMB, C-RMB, S-PMB etc. can.

2. The button action DOUBLE_CLICKED will always be preceded by a PRESS and a RELEASE action. This is the first "click" of the double click. It will also be followed by a RELEASE action. Thus a double click results in 4 actions:

PRESS

RELEASE

DOUBLE_CLICK

RELEASE
