Well, what can i say, it's definitely you. I have no trouble changing
component values.
Just doubleclick on the x-shaped handle, then it will "stick".
The checkbox in front of each field will select itself automatically if
you edit the field. The reason is simple, select and change several
components, and they may have many parameters different. But this way you
can change one parameter for all, while leaving the other parameters as
different as they were.

It's not only the ä key, you can go via the menu (something like
edit/change), or use @ instead of ä.
It probably says the right key to use in the english menu. I don't have an
english version installed.

All packages should use standard pin counting, or things will get
complicated. There is no need to make several footprints with ECB BCE
etc.. You just edit the pin numbers for the schematic symbol, and stick to
the conventional counting for the pins, like used in datasheets. Yes you
must correlate it for every part, and it is always dangerous to use
pre-made lib parts, check it to be safe. (i had that trip me up even in
orcad, where they provided errorous library parts).

You can do that in target, there's a helper where you can make like "5
pads 100mil apart round shape 2mm diameter starting at x/y" etc. I rarely
use it though because i'm faster just editing them on the drawing sheet.

Just do the tutorial or something, or read the help. From your coments i
can see not even the most basic things work out for you, which i can
assure you is a usage problem.
