Drag and drop an image or a directory of images onto a pane, and navigate through the images using the A / D keys or the slider UI. Use the mouse wheel to zoom in/out of an image.

In dual-pane mode (Ctrl + 2), the slider syncs images in both panes by default. You can switch to per-pane sliders by selecting the "Controls -> Controls -> Toggle Slider" menu item or pressing the Space bar.

• Arrow keys (Left / Right) or A / D: Show previous / next image
• Shift + arrow keys (Left / Right) or Shift + A / D: Render previous / next images continuously ("skate" mode)
• Tab: Show / hide the slider and footer UI
• Space: Toggle between single slider and dual slider
• 1 and 2 keys: Select Pane 1 or Pane 2
• Ctrl + 1 or 2: Toggle between single pane and dual pane mode
• Ctrl + W: Close all panes
• Ctrl + Q: Exit

ViewSkater's slider UI was inspired by the open-source project emulsion.
