Instructions
 
Hint: You may have to click on the grid before entering the very first letter.

Puzzle grid movement

Using the keyboard:
The Arrow keys are the primary movement keys for moving through adjacent cells. Word direction (Across or Down) is switched automatically based on the direction of motion.
Tab and Shift-Tab keys move one word at a time forward and backward respectively in the current direction. Enter/Return key moves to the next word in the current direction.

Using the mouse
 
Click and drag in the Across or Down direction (at least one cell over in that direction) to select a word for entry in the corresponding direction. Clicking on a single cell without dragging will use the current direction. You can use right mouse button (when available) or Shift/Ctrl keys in conjunction with any mouse button to switch directions. Click on any clue in the clue list to select the corresponding word.

Clue list scrolling

Click on the arrow keys next to the clue lists for quickly scrolling a clue-list a "page" at a time. Click on any clue on the clue list and drag up or down with the mouse for smaller amounts of scrolling.

Solution checking and revealing

Clicking on Check (icon at the bottom left corner) will check all letters and mark the incorrect ones only. Subsequent re-editing of cells marked as incorrect will have a black mark in the top right corner to remind you that it was checked earlier. Clicking on Reveal (icon at the bottom left corner) will reveal the complete solution and mark the incorrect ones or unfilled squares with a red mark in the top right corner.
