Thank you, I missed that, I'll see to it that it is fixed soon, still work in progress .

Good point but to be honest I much more commonly use LN and LOG than e^x and 10^x and they even have alternatives like e ^ and EXP. On my HP49G+ they are on the same level while on RealCalc LN and LOG are main keys.

What do you think about history, is it be useful?
