[improvement] improve text editor navigation

[bug] editor freezes after some idle time

This typically happens in complex setups with PipeWire, where a bridge between different devices, such as the wireless mic and the internal headphone jack, is created.

2.) The editor is accepting input, but executing code doesn't have any effect ...

Segfault when running release binary

I'm getting a segfault when I try to run the pre-built binaries.
