Node creation in accessibility tools not functioning properly

[ndoschek]

The node creation process within the accessibility tools is currently broken.
When attempting to create a node using keyboard shortcuts, the process cannot be completed as expected.

Steps to Reproduce:

1. Optional: Open the help menu: Alt + H
2. Focus on the tool-palette: Alt + P
3. Select "Manual Task" using F and attempt to place it in grid 4.
4. Notice that the position indicator cannot be moved, and pressing Enter does not complete the creation process.

Expected Behavior:

• The position indicator should be movable using the keyboard. It should also indicate if the current position is valid to create the element.
• Pressing Enter should complete the node creation.

I suspect this might be a focus-related issue, as the focus indicator shows "Currently focused: unknown," but I haven't investigated the problem in detail yet.
