Pan (shortcut: SPACE)

The Pan tool will display the current memory region shown on screen, and the address your cursor is currently pointing at.

Hold down the left mouse button to drag the screen up or down. The right button/mousewheel can also be used, even when a different tool is selected.

Holding SHIFT will show the current address at the cursor.

Select (shortcut: M)

The Select tool works about how you'd expect. Click and drag to select.

By default, your selection will be treated as though it were GFX - the selection region will be square, and you can even paste your data into the regular PICO-8 sprite editor!

Holding SHIFT while making a selection instead enters an alternate mode that allows you to copy the data as a raw series of bytes, saved to the clipboard as a binary string.

Stamp (shortcut: V)

Pressing CTRL-V will load data from the clipboard into memory. Left click to place it on the screen.

As with the Select tool, GFX copied from the PICO-8 sprite editor is supported.

Save Cart (shortcut: S)

Entering a filename into the Save Cart menu (loaded cart is entered by default) will CSTORE the entire ROM you have loaded to it, including any changes made.

Export as Screenshots (shortcut: P)

The "Export as Screenshots" button will save the entire visualization as 3 screenshots at 1x scale.
