I wanna set a a keyboard that sends a "1"

keyboard and a "2" keybord,, also ... another keyboard that does the same ... ( sending "1" and "2" keyboard ) .. how will i know which keyboard generated those numbers ?

Replace keyboard after clicking on button?

another example is that ... i wanna send a keyboard which sends multiple documents .... each document has chatptre 1 , chaptre 2 ... soo how will i know which chapter to send ?

Inline keyboard buttons have a display value and a data value. So you can just use different data for the second inline keyboard.

alright , but the normal keyboard , no ?

Same thing exactly

how ?

I'm confused now can you send screenshot example?

yeap

You want change the keyboard with new one after chosing an option?

yes , and this one is the same for all keyboard in therme of the name.. but generates differente data according to the last keyboard clicked

Last time I checked (several years ago) the only possibility was to save on your side, what the last keyboard for the user was.

What's mean different data here?

Thanks i will see how ..

imagine your studying at an university ... it has multiple courses .... each course has chaptre 1 , chaptre 2 .... your bot in the end will receive the keyword " chaptre X " .. how will it know which chaptre of which courses to send ? .. does telegram sends the " last clicked keyboard " clicked or any other way to know the precedent data .. that was my question but thanks i wil check api

Sorry but so far I don't understand If you have bot example have what you want

ok thx
