Scrolling history for commands and searches have been added to the MakeItC and BASICtools.
While Tod was working with his talking BASIC ARM projects, he found he needed history for commands sent to the text to speech module. So he took our published TclTk source and added a scrolling through the last 20 commands entered.
I took a look at what he did, and saw that the scrolling feature was indeed very useful. So that feature was made part of our release, and also added that to the Search Box.
And now after you have entered some commands or searches, use the up and down arrows to scroll through prior entries.
