Scenario 1 (correct, IMHO)

1. In the music editor, use the keyboard to select a note in a channel
2. Switch to the SFX editor using the keyboard (Alt + left)

Result: The SFX which the cursor was in (in step 1) is selected in the SFX editor.

Scenario 2 (correct, IMHO)

1. In the music editor, use the keyboard to select a note in a channel
2. Switch to the SFX editor using the mouse (click on the SFX tab)

Result: The SFX which the cursor was in (in step 1) is selected in the SFX editor.

Scenario 3 (correct, IMHO)

1. In the music editor, use the mouse to select a note in a channel
2. Switch to the SFX editor using the keyboard

Result: The SFX which the cursor was in (in step 1) is selected in the SFX editor.

Scenario 4 (bug, IMHO)

1. In the music editor, use the mouse to select a note in a channel
2. Switch to the SFX editor using the mouse (click on the SFX tab)

Result: The SFX which the cursor was in (in step 1) is NOT selected in the SFX editor. It looks like whichever SFX was previously selected in the SFX editor is there...or something. It's not what I expect.

Summary

• If the keyboard is used to select the note in the music editor, that SFX will be selected when switching to the SFX editor regardless of whether keyboard or mouse was used to switch to the editor
• If the mouse is used to select the note in the music editor, that SFX is only selected if switching to the editor with the keyboard, which feels unintuitive/buggy.
