How to reproduce:
1. Open provided example project
2. Open Assets/Scene.unity
3. Select "New Sprite" in hierarchy window
4. Open the "Select Sprite" dialog for the Sprite Renderer that is shown in the Inspector
5. Type "Hello" in search text field of the Select Sprite dialog
6. Press Pos1 (Home) key
=> Notice it's ignored
7. Hold Shift and press Pos1 (Home) key
=> Notice it's ignored
8. Press Ctrl+A and notice this hotkey works to select the entire text
9. Press End key
=> Notice it's ignored

To see the expected behavior try all hotkeys in project search

Workaround: Use other hotkeys: Ctrl+A and Arrows
