.Sh DESCRIPTION
|
|
The
|
|
.Nm mcon
|
|
utility controls the configurable parameters for the mouse emulator of
|
|
.Xr pcvt 4 .
|
|
.br
|
|
.Em NB :
|
|
The mouse emulator is not configured in by default; the system's config
|
|
file needs to specify an option line
|
|
|
|
.Em options Dq PCVT_EMU_MOUSE
|
|
|
|
in order to get its functionality.
|
|
.Pp
|
|
Either way, the
|
|
.Nm
|
|
program must be called with an argument
|
|
.Ar device
|
|
that specifies the device node used for the mouse emulation. This is
|
|
usually the first device node of the
|
|
.Xr pcvt 4
|
|
driver not being used as a virtual terminal device. E.\ g., if you
|
|
have configured eight virtual terminals
|
|
.Pq the default value ,
|
|
named
|
|
.Pa /dev/ttyv0
|
|
through
|
|
.Pa /dev/ttyv7 ,
|
|
the mouse emulator would allocate
|
|
.Pa /dev/ttyv8 .
|
|
|
|
If
|
|
.Nm
|
|
is called without any option, it will print the actual values of the
|
|
configurable parameters.
|
|
|
|
If called with an option, the program attempts to set up the new value.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Fl l Ar left-button-key
|
|
.It Fl m Ar mid-button-key
|
|
.It Fl r Ar right-button-key
|
|
Maps the named
|
|
.Ar button key
|
|
to emulate either the left, middle, or right mouse button.
|
|
.Ar Button key
|
|
is the usual name for that key. Normal ASCII keys are denoted by the
|
|
character they're labeled with, function keys are named
|
|
.Em f1
|
|
through
|
|
.Em f10 .
|
|
Note that the AT function keys
|
|
.Em f11
|
|
and
|
|
.Em f12
|
|
are
|
|
.Em extended
|
|
keys that cannot be mapped to be used with the mouse emulator since
|
|
it only allows basic PC-scancode keys to be used.
|
|
|
|
.It Fl a Ar accel-time
|
|
Set the time limit for the internal accelerator to
|
|
.Ar accel-time
|
|
milliseconds. Key events occurring after a longer time than this limit
|
|
will move the mouse cursor in single steps. Key events arriving more
|
|
frequently will move the cursor accelerated by a factor of 6. Note that
|
|
despite of
|
|
.Em milliseconds
|
|
being the unit of choice here, the time resolution is restricted by the
|
|
timer tick distance of the underlying operating system, usually to a
|
|
granularity of 10 milliseconds.
|
|
|
|
.It Fl s Ar 0 | false | \&no
|
|
.It Fl s Ar 1 | true | yes
|
|
The first form disables, the second form enables the
|
|
.Em sticky
|
|
behaviour of the mouse buttons. Sticky mouse keys behave much like
|
|
toggle-buttons: on first press, they become active, on second press,
|
|
they're deactivated. Pressing another button will deactivate any
|
|
other sticky button anyway.
|
|
|
|
Sticky buttons might be more convenient since you don't need 20 fingers
|
|
at all; on the other hand, they make it virtually impossible to initiate
|
|
double or triple mouse clicks.
|
|
.El
|
|
.Sh EXAMPLES
|
|
The following example would install the default behaviour of the
|
|
mouse emulator:
|
|
|
|
.Nm mcon
|
|
.Fl l Ar f1
|
|
.Fl m Ar f2
|
|
.Fl r Ar f3
|
|
.Fl a Ar 250
|
|
.Fl s Ar \&no
|
|
.Pa /dev/ttyv8
|
|
.Sh BUGS
|
|
The key names used to map the button-emulating keys to scan codes
|
|
.Pq and vica verse
|
|
are based on the American keyboard layout. This would usually not
|
|
cause any trouble since the
|
|
.Dq button-of-choice
|
|
is certainly some function key that should be equal for any national
|
|
keyboard layout.
|
|
.Pp
|
|
The mouse emulator is a rude hack at all; its only purpose is to provide
|
|
a device to move the pointer within an X-windowing environment.
