Hi there,
I have
'(transient-mark-mode t)
in my custom-set-variables and for each of the four arrow-keys of my
keyboard i have a function of the following kind in my .emacs file and i
bind the according function to the corresponding arrow-key:
(defun set-mark-and-move-point-right ()
"sets mark if mark is not set and move point one line up"
(interactive)
(when (not (region-active-p))
(call-interactively 'set-mark-command)
)
(forward-char 1))
region-active-p looks like that
(defun region-active-p ()
"Say whether the region is active or not."
(and (boundp 'transient-mark-mode)
transient-mark-mode
(boundp 'mark-active)
mark-active))
i achieve the desired behavior that the region is activated and
colorized by transient-mark-mode when i press shift-<some_arrow>.
However i have the feeling that this is not a clean way to achieve this
since using these functions I a can also
press shift-<arrow>
release shift already
press some <arrow>s and region is still colorized
call for help is like this: Can it be done better? Is it possible to
de-activate the region when shift is released?
thanks for your help.
