I try with this action
to leave the menu open. Like this.
This would be useful because I could select something without a shortcut
Is there any way to do this?
Unfortunately (or luckily) the used API doesn't really open the menu, thus this is not possible. (It works for top level elements like in your example "Darstellung". So you could trigger "Darstellung" and then send a few arrow down events.
Ja, danke, so geht's
