Accordance 10.4 on Windows 8.1 x64:
These issues haven't been addressed in 10.4:
1. Arrow Keys
ALT+Left/Right Keys: cursor still jumps between words
CTRL+Left/Right Keys: cursor still jumps between beginning and end of line
Expected behavior in Windows:
ALT+Left/Right Keys: does nothing/not assigned (there are keys pos1/end for to jump to beginning/end of line)
CTRL+Left/Right Keys: jump between words
2. Switching between word/verse search (CTRL-SHIFT-, on German keyboard)
Still doesn't work on the German keyboard.
It works on the Mac version by the way (with the corresponding mac modifier keys).
