[Bug]: Ctrl+PgUp Not registering

[TakemiSora]

Problem description

Attempting to press Ctrl and/or Alt with PgUp/PgDown does not send the correct keys to the shell.

In the video, the other app besides termux is AVNC client connected to vncserver from termux. Where you can see that pressing ctrl+pgup makes ^[[5;5~ appear where as in termux it just sends the PgUp.

Steps to reproduce the behavior.

• Open Termux App
• Use showkey -a or cat -v
• Attempt to press Ctrl and then PgUp (and also just PgUp)
• Both will return the same output

What is the expected behavior?

The correct keys should be sent.

System information

• Termux application version: 0.118.3
• Android OS version: 16
• Device model: Motorola Edge 50 Fusion

According to my testing (on this device: Samsung Galaxy S III SPH-L710 Android 7), this issue is not reproducible in the version 0.119.0-beta.3 if using only this keyboard https://f-droid.org/en/packages/org.pocketworkstation.pckeyboard/ however, it is reproducible with no known workaround in the version 0.118.3.

however, if using the built in extra keys bar version of the PGUP button, instead of the https://f-droid.org/en/packages/org.pocketworkstation.pckeyboard/ version of the PGUP button, this problem is reproducible in all versions of Termux.

In Termux version 0.119.0-beta.3, I see these behavior results:

CTRL	PGUP	cat output	OK
EK	EK	^[[5;5~^	🟩
HK	HK	^[[5;5~^	🟩
EK	HK	^[[5;5~^	🟩
HK	EK	^[[5~	🟥

this is believed to be because the Hacker's Keyboard CTRL button is not compatible with the Termux Extra Keys buttons, and this might not be fixable on the Termux side.
