@oyMarcel Look for the section where constants are defined. The C syntax is static const char *pointer.

@ahmedsamyh You'll need to write a small script or program in the language of your choice that executes what you need and map it to a key combination in your keyboard, I advice you write another to undo it as well ;-).

Worked like a charm!

Amazing! Thanks.

This works! Thanks.

PERFECT

That helped me. Thank you so much :-D

In case you use amixer:

static const char *upvol[] = { "/usr/bin/amixer", "set", "Master", "5%+", NULL };
static const char *downvol[] = { "/usr/bin/amixer", "set", "Master", "5%-", NULL };
static const char *mutevol[] = { "/usr/bin/amixer", "set", "Master", "toggle", NULL };

Check the +/- position

i used amixer long time ago but thanks :)

how do i install the x11 dev thing on arch?

GOD BLESS YOU DUDE!

If you're using pulse and your default is not always the same, use:

static const char *upvol[] = { "/usr/bin/pactl", "set-sink-volume", "@DEFAULT_SINK@", "+5%", NULL };
static const char *downvol[] = { "/usr/bin/pactl", "set-sink-volume", "@DEFAULT_SINK@", "-5%", NULL };
static const char *mutevol[] = { "/usr/bin/pactl", "set-sink-mute", "@DEFAULT_SINK@", "toggle", NULL };

@GabrielHenri39 bro stop this is the wrong place to write your Django code
