Send multiple same keyevents to the adb shell?

How can you send multiple key events to the adb shell of the same key? For example, you can issue one 'delete' key event (#67) like this:

adb shell input keyevent 67

But is there something like this (note: this won't work)?

adb shell input keyevent 67 67

If you are concerned about speed, I suggest using the sendevent command to send an event. I've found it to be significantly faster especially when it comes to simulating a tap.

Example

sendevent /dev/input/event18 1 67 1 // send key down event 67
sendevent /dev/input/event18 0 0 0  // end of report
sendevent /dev/input/event18 1 67 0 // send key up event 67
sendevent /dev/input/event18 0 0 0  // end of report

SYNTAX

sendevent <device> <type> <code> <value>

NOTE

This is sending events at a low level, which can give a lot of control and also flexibility to make it efficient by sending the exact events you are interested in. A big drawback, in my opinion, is the fact that you'll have to determine the device on your own (probably by using getevent command and manually figuring it out) The device /dev/input/event18 is just an example I used from my phone, this isn't constant.

For reference to valid arguments, you can see the header file. https://android.googlesource.com/platform/external/kernel-headers/+/8bc979c0f7b0b30b579b38712a091e7d2037c77e/original/uapi/linux/input.h

Try to use

adb shell "input keyevent 67 && input keyevent 67"

If you need to write large scripts, you can also try this approach.
