**Alt Up** to recall previous commands to the current input line

In Matlab and RStudio, I love the ability to recall a command I’ve already typed using the up arrow key. Today I discovered **alt up arrow** to do the same in wxMaxima!

### Ctrl Shift K for autocomplete and function template

This is really the best implementation of function templates I’ve seen in an IDE:

In wxMaxima, if I type *inte* and then** ctrl shift k**, I see a popup menu of possible completions. Choosing integrate results in an input cell template that looks like:

**integrate(<expr>,<x>)**

Pressing Tab highlights <expr> and I simply type the expression to be integrated. A second press of Tab key highlights <x> and I type the name of the independent variable.

But wait, there’s more: this works for any currently defined function—including user defined functions.
