Auto-click the mouse while specific keyboard button is held down

Question

I have a game that requires me to click a moving object repeatedly, which is extremely difficult if you only have a touchpad with no separate mouse buttons.

What I want is to have a tool/script that repeatedly emulates a mouse click (left button, maybe around 5 clicks per second) while a specific keyboard button or combination is held down, e.g. Control (right)+Menu.

I know I can emulate repeated clicks with a command like

xdotool click --repeat 10 --delay 200 1

but I have no idea how to make it click while a specific keyboard combination is held down instead of a fixed number of clicks.

Answer 1

Here's my first and fifth attempts. The first is decent if you don't need to change the delay. It seems to have some problems with certain key combinations, not sure what was causing it however.

Method 1, in ~/.xbindkeysrc:

keystate_scrolllock = enable

"xdotool click 1"
    Scroll_Lock

Method 5:

keystate_scrolllock = enable

"/home/USER/infinite_clicks.sh event16 KEY_SCROLLLOCK 0.1 &"
    Scroll_Lock

With infinite_clicks.sh being:

#!/bin/bash
kbd=$1 #"event16"
key=$2 #"KEY_SCROLLLOCK"
delay=$3 #"0.1"
fn=`basename "$0"`

if [  $# -le 1 ]; then 
    echo "Usage: $fn input_device key_name delay"
    echo "Example: $fn event16 KEY_SCROLLLOCK 0.1"
    echo "Must run as superuser."
    exit 1
fi 

# do not start if already started
if [[ $(pidof -o %PPID -x $fn) ]]; then
    exit 0
fi

while true; do
    # this is why you need to use sudo/superuser
    evtest --query  /dev/input/$kbd EV_KEY $key

    # get evtest return code, if it's 0 the key is up
    if [[ "$?" -eq "0" ]]; then
      break
    fi

    xdotool click 1 &
    sleep "$delay"
done

exit 0

With this code you also need to run xbindkeys as sudo xbindkeys -f ~/.xbindkeysrc

You can find your keyboard event number using sudo evtest then find the key names using sudo evtest /dev/input/eventXXX using the event number.

I've been using ClickItAuto,a little program which, as any Java software, can be executed in multiple OS

There are various auto clicker software available online to download.

I recommend for you Max Auto Clicker because is a cross platform application (Linux + Windows), free and safe to use.
