getKey command

[math7]

Hi, is there a command programming on the calculator or LUA command to get the code of a key pressed in the Nspire? This would be very helpful in making the keys are programmable, I saw that this command does exist on the TI-84, the getKey command.

[Steve Arnold]

on.charIn(key) will do just this.

Tutorial 4 covers this:

With best wishes,

Thank you very much Steve, I believe that this event serves me partly because I need to be captured when you press any key, for example the [+] or [EE] but on.charIn I think it only serves to characters or not? 

Kind regards, 

[math7]

I would like to make a program to assign a formula or program to a specific key and when to run after the arguments put Realize the function I assigned to the key, ie each key on the Nspire can perform more than one function combination with the [ctrl] or [shift]

[Steve Arnold]

I think you will find that charIn recognises any character typed or entered from the keyboard. So ones like the EEcomes through as E. If you wanted to set up a condition involving special characters like this, use the Symbol Palette in, say, a Notes page. Enter the character, then copy and paste it into your script.

Should work fine.

With best wishes,
Steve

And what do non-character keys produce?

Sorry, I'm not at a computer to test it.

It works too :

I tested some unusual things : 

sin(

=

^

^2

10^(

exp(

(

)

*

[ [,] [,]]

/

-

+

"

With the 3.2 software, add a lua script with only this : 

on.charIn = print

and press a key (directly on your keyboard or on the smartview frame). its corresponding value will be printed in the console.

[math7]

yes already tried it and it works for almost all the keyboard, but not to enter keys, ctrl, shift, etc..

 thanks to all

[math7]

HOla Steve, could you give me an example how to do that in the Notes application? thank you very much

[Steve Arnold]

Sorry - Lua only. Can't do it in Notes unless you store a variable from Lua and then display in a MathBox?

Also, Lua cannot recognise shift, ctrl etc key additions as far as I know. 

With best wishes,
Steve
