Thanks to the contribution from [francescoaru], the Shell component now has a history function:
This means (if enabled), the Shell component remembers the last few commands. Entering any non-alpha/numeric character (e.g. TAB, CURSOR-UP/DOWN/LEFT/RIGHT, etc) will show the previous command, and you can iterate trough the list. Press Enter and it gets executed. This is especially useful if you are using a terminal program like putty without history: E.g. pressing TAB will show the previous command:
Then press TAB again, or simply ENTER to execute the command. You can use the cursor up/down/left/right keys to go forward and backward in the list of history, then press ENTER to execute the command.
There is one ‘not so perfect thing': if pressing cursor-up and then cursor-down, it will show the command again. But I hope this is not a big deal, otherwise any contributions to improve this are welcome :-)
Happy Historing :-)
