Whisker Menu and Super keys

A little help please. I want to run Whisker Menu plugin with Super_L and Super_R keys.
I removed the old Whisker Menu keyboard shortcut first.
That way it won't interfere with the sript. With this script below I monitor X keyboard input.
If one of the Super keys is pressed and released it will show or hide the Whisker Menu.
Now, if I press some key combo, like Super_L+F, It launches whatever command is set.
That's alright, but when I release the Super key, Whisker is being shown.
How do I filter out the key-combos so that Whisker doesn't launch?

#!/bin/bash

  xinput test-xi2 --root | perl -lne '
    BEGIN{$"=",";
      open X, "-|", "xmodmap -pke";
      while (<X>) {$k{$1}=$2 if /^keycode\s+(\d+) = (\w+)/}
      open X, "-|", "xmodmap -pm"; <X>;<X>;
      while (<X>) {if (/^(\w+)\s+(\w*)/){($k=$2)=~s/_[LR]$//;$m[$i++]=$k||$1}}
      close X;
    }
    if (/^EVENT type.*\((.*)\)/) {$e = $1}
    elsif (/detail: (\d+)/) {$d=$1}
    elsif (/modifiers:.*effective: (.*)/) {
      $m=$1;
      if ($e =~ /^Key/){
        my @mods;
        for (0..$#m) {push @mods, $m[$_] if (hex($m) & (1<<$_))}
          # Comment out next line to see what key is pressed
          # print "$e $d [$k{$d}] $m [@mods]";
          if (($k{$d} eq "Super_L" or $k{$d} eq "Super_R") && $e eq "KeyRelease"){
             system ("xfce4-popup-whiskermenu > /dev/null 2>&1");
          }
      }
   }'

Re: Whisker Menu and Super keys

I use Ksuperkey to do that. Despite the name it isn't part of KDE. See https://github.com/hanschen/ksuperkey

Re: Whisker Menu and Super keys

- Launch Settings->Hardware->Keyboard->Application Shortcuts and click the "Add" button
- Type: xfce4-popup-whiskermenu
- Press the Left Super key when prompted for a keyboard shortcut.
- Repeat the process for the Right Super Key

Here is another cool trick Open up a terminal and run this command: xfce4-popup-whiskermenu --pointer

Xfce4 rules!

Nice tip marko.

New for ARCH and DEBIAN, bit Linux Mint has LEFT SUPER key for that by default.

Re: Whisker Menu and Super keys

No worries, what you can also do is, should you wish to use a dock instead of the panel (personally, I have to have the panel + a window button list, please keep this as an option), you can add a custom command to the dock and the command would be: xfce4-popup-whiskermenu --pointer and the menu would pop up right there where you click the button.

Thank you ozjd. That's one neat little tool. As long as it is running it does what is advertising.

- Launch Settings->Hardware->Keyboard->Application Shortcuts and click the "Add" button
- Type: xfce4-popup-whiskermenu
- Press the Left Super key when prompted for a keyboard shortcut.
- Repeat the process for the Right Super Key

I had some trouble with the Super_L key and overlaping with keyboard combo shortcuts on this 4.10 xfce.
