It seems to me that toolbar would be the place for such things, rather than something platform specific.

Actually we could even have toolbar buttons for event-apply-control-modifier and so on. Then a normal keyboard could work very well.

Although moving the toolbar to the bottom of the screen on Android (as I saw some feature mentioned) would help with that. And increasing the size of the icons...

Yep, you've just described platform-specific UI details. How the Android port implements that (natively in Java or with Lisp using the standard toolbar) is secondary, but adapting to the specific form-factor (and the proximity to the on-screen keyboard) has its benefits.

Eli mentioned JuiceSSH (which for some reason doesn't install on my phone, listing itself as "not available") and it has this on the screenshots: https://play-lh.googleusercontent.com/1rhvZxZHx_IraiVLzqjYHwM1M3lm_HRsTCd_S4VSyEqzr-uNqThx63MtSdrgpDEJBos=w5120-h2880. IOW, a bunch of special keys that usually have Emacs bindings but are absent on the standard on-screen keyboards.

Here's also a screenshot of Termius: https://play-lh.googleusercontent.com/XUYZvSuW9FH9WbwHuZVkhgb5f1Qgx-2WZy_fkQJhziiiA7PS0yw7rywz2vm0RlQCLwSN=w5120-h2880

It also provides easier access to some of those buttons. I haven't installed either yet, so not sure how they are implemented (keyboard hints or not), maybe also rendered in-app.

And here's another example: https://play-lh.googleusercontent.com/ZjqY_bYIuWan8ZHOU7Cv0utQEe6j0wRg50nr8c5_WVS2KBvklragHcD_aWm_KJg8RW7o=w5120-h2880

That's xterm app inside DaRemote. While it has 2 rows of buttons, it's still pretty compact.
