Inline "on the fly" calculations

Hello, is there a way to have textblaze function as a basic "in-line calculator?"
ie, type in a calculation such as 8*7 (then trigger the result, 56) then type in ^2 (then trigger the result), etc etc. If so, sorry if I've been living under a rock. If not, that would be a pretty cool feature.

Thanks.

Yes, you can.

Create a lambda function from a string and then call it:

{formtext: name=eq; default=1+1}

= {=("() -> " & eq)()}

Nice. thanks.
