There is no sound feedback when moving vectors using the keyboard. Sound is only played when dragging vectors with the mouse, but it is not triggered during keyboard-based movement.

There are also no sounds for the toolbox, deleting a vector, or the Alt+C shortcut.

For manipulating vectors, we lost default (grab/release) sounds when I converted keyboard input from SoundDragListener to KeyboardListener. For the other things, it was an oversight. And we should have had a design discussion about which sounds to use.

@matthew-blackman and I discussed sounds. Here's the sound design:

Toolbox buttons:

• space, enter: same as PushButton since slots have tagName: 'button' (pushButton.mp3)

Vectors:

• arrow buttons, WASD: default grab/release sounds (grab.mp3 on press, release.mp3 on release)
• space, enter: checkbox sounds (checkboxChecked.mp3, checkboxUnchecked.mp3)
• delete, backspace: EraserButton sound (erase.mp3)

@matthew-blackman please review in main. Assign back to me so that I can patch the 1.2 branches.

Tested in main and confirmed the following sounds:

• Adding a vector from the vector toolbox to the graph area plays the push-button-down sound - sounds good.
• Grabbing and releasing a vector plays the drag sounds - sounds good.
• Returning a vector to the toolbox plays the erase sound - sounds good.
• Selecting and unselecting a vector plays the checkbox checked/unchecked sounds - sounds great.
• Checking values with Option-C uses the combo box 'open' sound - also sounds great.

Everything looks good and sounds great on my end. Nice work! Assigning back to @pixelzoom.
