Hi Stefan,
thanks for testing..
* the command word is doubled (>dirdir)
with duplicate - this is downport problem... Because I need to support 1.4x and 1.50 now, and do development in 1.50 as far version differ, as more complex to integrate changes from 1.50 to 1.4x...
There are no duplicates in 1.50 but probably during downport something was integrated incompletely.
Another reason for not doing new features in correction branch...
I would fix this new beta. Reproduced.
* the command CLS didn't work
CLS is cmd command, but I not emulate console but only catch output. Do not know is it possible, but would check.
* the command CTRL+X insert an up-arrow (see picture)
Probably I need to implement not only Ctrl+C but also Ctrl+X

* in InOutput-Dialog-context menu an Paste item is missed (maybe)
Yes, can be added.
Saying the truth, I was not planning to do a lot here, just have tried to solve problem with
pause. but at the end have implemented all that stuff. Would be better to do this in 1.50 where I have planned more (for example multiple, parallel running outputs).
So, I would try to add to input functionality in 1.4x only minimum, and the rest of request would go to 1.5x.
