Hello, first post. I am coming from using the TI89 previously.

I know I can create functions on the Nspire. But can I create a menu?

One thing that I was able to do on the TI89 was take my most frequently typed commands and put them into a menu.

For example, I use rref([][][]) all the time to solve systems of 3 variables. So I could literally have  rref([][][]) be a menu item, and I just fill in the blanks.

Can I do such a thing in the Nspire?

Also, is there a way to create a function or variable that stores EMPTY elements? Such as in the case of rref([][][]). If I could just type a command and have that text appear, then I could fill in the blanks.

Thanks in advance.
