Description

I don't quite understand how to use .KeyToggle. When I want to enter ctrl + j for about 1200ms, I use KeyToggle like above code, however, it seems that only ctrl button is pressed for a long time and j button is only pressed for a very short time. Firstly I only wrote

robotgo.KeyToggle(keyMap[rnode], "down", add)

When I found it's not working, I added robotgo.KeyToggle(keyMap[rnode], "down") above just like what example/key/main.go did, but it's still not working. the keyMap[rnode] button is still pressed for a very short time, and the err is empty when I want to catch it if KeyToggle error happened. I can make sure that add="ctrl" because I used fmt.Println(add) to ensure it and the keyMap[rnode] is what I want. So is it because I'm confused with .KeyToggle's usage?

Hi there, about your confused:

• How to use .KeyToggle

// press 'j'
robotgo.KeyToggle("j", "down")
robotgo.KeyToggle("j", "up")
// press 'ctrl+j'
robotgo.KeyToggle("j", "down", "ctrl")
robotgo.KeyToggle("j", "up", "ctrl")

• Why pressed for a very short time

// press 'j'
robotgo.KeyToggle("j", "down")
robotgo.MilliSleep(5*1000)    // the key 'j' is pressed, but not equal to press many times
robotgo.KeyToggle("j", "up")
// press 'ctrl+j'
robotgo.KeyToggle("j", "down", "ctrl")
robotgo.MilliSleep(5*1000)     // the key `ctrl`and 'j' is pressed, but not equal to press many times
robotgo.KeyToggle("j", "up", "ctrl")

• How to enter ctrl + j for about 1200ms You can use go channel, for example:

package main

import (
	"fmt"

	"github.com/go-vgo/robotgo"
)

func main() {
	done := make(chan bool)
	go func() {
		for {
			select {
			case <-done:
				robotgo.KeyToggle("j", "up", "ctrl")
				return
			default:
				robotgo.KeyToggle("j", "down", "ctrl")
				robotgo.MilliSleep(10) // It's better to sleep 10 milliseconds
			}
		}
	}()
	robotgo.MilliSleep(1200)
	done <- true
	fmt.Println("done...")
}
