Keyboard Navigation Tips

1

Learn Core Shortcuts First

Master Spacebar, J, and arrow keys before exploring others
2

Use ASDF for Effects

The four effect keys (A, S, D, F) are on the home row for easy access
3

Number Keys for Tracks

Memorize your favorite ambient tracks (1-9) for instant access
4

Keep Hands on Keyboard

Rarely need mouse/trackpad once shortcuts are learned

​
Context-Sensitive Behavior

Some shortcuts are context-aware:
When typing in an input field:
  • Most shortcuts are disabled
  • Esc still works to exit
  • Letter keys type normally
  • Arrow keys move cursor (not background)
This prevents accidental actions while typing.

​
Visual Feedback

Shortcuts provide immediate visual feedback:

Button States

Effect buttons change color when active

Settings Panel

Slides open/closed with animation

Background Change

Instant transition to new image

​
Accessibility

Keyboard shortcuts make LoFi Engine fully accessible:
  • No mouse required: Full control via keyboard
  • Screen reader compatible: All actions announced
  • Visual indicators: Button states show active/inactive
  • Logical grouping: Related shortcuts use nearby keys
The ASDF row for effects (A=rain, S=thunder, D=jungle, F=fire) follows left-to-right logic and keeps your hands on the home row.

​
Custom Shortcuts

LoFi Engine does not currently support custom keyboard shortcuts. All shortcuts are fixed in the application.
If you need different keybindings, consider:
  • Using OS-level keyboard remapping tools
  • Browser extensions for custom shortcuts
  • Accessibility tools for alternative input methods

​
Troubleshooting

If shortcuts aren’t responding:
  1. Check focus: Click anywhere in the app window
  2. Close dialogs: Press Esc to exit info/settings
  3. Exit input fields: Click outside any text fields
  4. Reload app: Press Ctrl + R to restart
If arrow keys move cursor instead of changing background:
  • You’re likely focused in an input field
  • Press Tab or Esc to exit the field
  • Arrow keys should then control background
Same as above - exit any active input fields first.
