How does one give .desktop files keyboard assignments in XFCE 4.16?

I have two self-coded .desktop files for monitor rotation, and I would like to assign keyboard shortcuts to both.
One rotates my HDMI-0 left, the other back to normal. (I also have .desktop's for right and inverse but hardly ever use these.)

Code: Select all

guest@porteus:/usr/share/applications$ ls -o monitorrotate-[ln]*|cut -c 19-
207 2021-01-22 18:55 monitorrotate-left.desktop
211 2021-01-22 18:55 monitorrotate-normal.desktop

The command itself being either

Code: Select all

/usr/bin/xrandr --output HDMI-0 --rotate left

for rotate left and

Code: Select all

usr/bin/xrandr --output HDMI-0 --rotate normal

for rotate normal.

I saw somewhere option for assigning keyboard shortcuts in XFCE, but do not recall where, and not even recall if these could be used to assign keyboard commands to specific .desktop files.
If that is not possible, I hope it is possible to assign a keyboard shortcut to a specific command, e.g. to the as quoted above xrandr commands.

no words needed, I think.

The issue with using ^L and ^N is: some programs might also use these shortcuts.
Only one example: mousepad:

What would happen then? Would XFCE catch ^L and ^N and the program would not react?
Or would both the screen be turned and the program that also uses whatever ^L or ^N means to it and also do the ^N or ^L task?
Especially annoying when you meant to only do the program ^L or ^N task and not turn the screen…

Another question:
xflock4 is also part of my XFCE 4.16 setup as "Super + L" but when I press that nothing is happening. Could it be that keyboard shortcuts are disabled as long as I have the Keyboard / Application Shortcuts tab open?

About xflock4:
I looked into

Code: Select all

/usr/bin/xflock4: POSIX shell script, ASCII text executable

and it says there at the top of the code (disregarding the long comment at top since a comment is no code to be executed)

Code: Select all

# First test for the command set in the session's xfconf channel
LOCK_CMD=$(xfconf-query -c xfce4-session -p /general/LockCommand)

# Lock by xscreensaver or gnome-screensaver, if a respective daemon is running
for lock_cmd in \
    "$LOCK_CMD" \
    "xfce4-screensaver-command --lock" \
    "xscreensaver-command -lock" \
    "gnome-screensaver-command --lock"
do
    if [ ! -z "$lock_cmd" ]; then
        $lock_cmd >/dev/null 2>&1 && exit
    fi
done

so I looked into these 3 programs:

Code: Select all

guest@porteus:~$ which xfce4-screensaver-command
which: no xfce4-screensaver-command in (/usr/local/bin:/usr/bin:/bin:/usr/games)
guest@porteus:~$ which xscreensaver-command
which: no xscreensaver-command in (/usr/local/bin:/usr/bin:/bin:/usr/games)
guest@porteus:~$ which gnome-screensaver-command
which: no gnome-screensaver-command in (/usr/local/bin:/usr/bin:/bin:/usr/games)

And the 1st code is also returning NIL:

Code: Select all

guest@porteus:~$ echo $(xfconf-query -c xfce4-session -p /general/LockCommand)

guest@porteus:~$

No wonder then that nothing is happening when pressing the associated keyboard shortcut.

That means *devious face* I can erase all entries concerning xflock4 and re-use all previously assigned to xflock4 keyboard shortcuts for my monitor-rotating thingys.

And if you not use changes recall to save /home/guest/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml
e.g. to your $PORTDIR/rootcopy/ -> $PORTDIR/rootcopy/home/guest/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml

I split the rest of the posts into a new thread -
XFCE - slock and xfce4-screensaver -
since these are all about slock and xfce4-screensaver and no longer about "keyboard shortcut to .desktop or to command"

I changed all from HDMI-0 to VGA-0

some diffs on that /usr/share/applications/monitorrotate-* :

Code: Select all

guest@porteus:/mnt/live/memory/images/991-usr_local_bin-RECENT.xzm/usr/share/applications$ diff monitorrotate-inverted /usr/share/applications/monitorrotate-inverted 
2c2
< Exec=/usr/bin/xrandr --output HDMI-0 --rotate inverted
---
> Exec=/usr/bin/xrandr --output VGA-0 --rotate inverted
guest@porteus:/mnt/live/memory/images/991-usr_local_bin-RECENT.xzm/usr/share/applications$ diff monitorrotate-left.desktop /usr/share/applications/monitorrotate-left.desktop 
2c2
< Exec=/usr/bin/xrandr --output HDMI-0 --rotate left
---
> Exec=/usr/bin/xrandr --output VGA-0 --rotate left
guest@porteus:/mnt/live/memory/images/991-usr_local_bin-RECENT.xzm/usr/share/applications$ diff monitorrotate-normal.desktop /usr/share/applications/monitorrotate-normal.desktop 
2c2
< Exec=/usr/bin/xrandr --output HDMI-0 --rotate normal

guest@porteus:/mnt/live/memory/images/991-usr_local_bin-RECENT.xzm/usr/share/applications$ diff monitorrotate-right.desktop /usr/share/applications/monitorrotate-right.desktop
2c2
< Exec=/usr/bin/xrandr --output HDMI-0 --rotate right
---
> Exec=/usr/bin/xrandr --output VGA-0 --rotate right

and XFCE's keyboard settings via ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml :

Code: Select all

guest@porteus:/mnt/live/memory/images/992-rootcopy_5.0-RECENT.xzm/home/guest/.config/xfce4/xfconf/xfce-perchannel-xml$ diff xfce4-keyboard-shortcuts.xml  ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml

If you prefer the menu based way for the 2nd kind of settings - that is via

you jump through some loops. Cave! I chose donald's screenshot (too lazy to make and upload my own, his is suffice), his commands differ a bit from mine, I refer to mine below the same as in the [ code ]-blocks above.

● First you select the correct entry
● press [Edit]
● Edit the entry accordingly, e.g. from

Code: Select all

/usr/bin/xrandr --output HDMI-0 --rotate normal

to

Code: Select all

/usr/bin/xrandr --output VGA-0 --rotate normal

● then you got asked which keys shall be assigned to this command. Cave! This window you cannot move. In the above examples you need to recall if it was the command meant for Super+n or Super+l - press both keys at the same time until the window only displays Super+n in the case of the above example
● Then XFCE tells you that a command for Super+n already exists and gives you a choice between [/usr/bin/xrandr --output HDMI-0 --rotate normal] or [/usr/bin/xrandr --output VGA-0 --rotate normal]
● chose the one you want, in the above example I chose [/usr/bin/xrandr --output VGA-0 --rotate normal]

Now you are all set. And how easy it is via menu.
Compared to opening an editor and replacing all two entries of HDMI-0 with VGA-0 the menu way for both keys is so much quicker. </irony>
