WarLight supports a few hotkeys to make navigating the UI easier. Once you get used to the game, these can make playing easier.

Phase Manipulation

A - While building your turn, you can press the A key to advance to the next phase.
Q - While building your turn, you can press the Q key to go back to the previous phase.
Z - When done building your turn, you can press the Z key to commit your orders assuming you've advanced to the confirmation phase.

Control - While in the Attack/Transfer phase, you can hold down Control to cause clicks to initiate a deployment (just as would happen in the Deployment phase.) Many players prefer to just skip immediately to the Attack/Transfer phase and then deploy using this shortcut. This allows you to issue a deployment and the corresponding attack order at the same time rather than having to do all of your deployments separately from attacks.

Interface Elements

R - Clicks the Refresh button.
W - When watching the latest turn, you can press W as a substitute for clicking the Watch Turn button.
T - Shortcut to opening the Chat window. (Multi-player only)
G - Shortcut to opening the History window.
B - Shortcut to opening the Cards window.
P and M - Short for Plus and Minus, these are shortcuts for zooming in and out. These are useful for systems without mousewheel support.
Escape - Closes any open pop-up windows.

Arrow keys - Navigate around history of a game. Left/right arrow keys go forward/backward one turn, and up/down arrows go forward/backward one order.
Home key - opens up history to the first turn (or territory distribution in a manual distribution game)
End key - goes to the last turn (you may also wish to use escape to close history completely)
