iOS: Missing function keys like Alt and Shift

[ColdNSs]

Problem:
As a user of the terminal emulator on iOS, I often find myself unable to access certain function keys such as Alt and Shift. This limitation hinders my ability to efficiently execute commands and perform tasks within the terminal environment.

Solution:
The addition of support for Alt and Shift function keys in the terminal emulator on iOS.

Typically, the Alt-key behavior is achieved by pressing the ESC key once, and then pressing the key you want (that is the effect of the alt key)

I guess the main issue is that some apps perform a timeout on the ESC to tell apart [ESC] [SOMETHING] from [ALT-SOMETHING]
