[02. KEYBOARD TEST]
The Keyboard Test contains three subtests that test the computer's keyboard and mouse actions.
[01. Pressed key display]
When you execute this subtest, the keyboard layout is drawn on the display. When any key is pressed,
the corresponding key appears on the display. Pressing and holding a key enables the auto-repeat
function which causes the key's displayed character to blink.
Before executing the test, select Keyboard Type in the test parameters.
NOTE: The [02. Expansion memory], [03. RAM refresh] and [04. Stress test] test all memory area.
When the capacity of mounted memory is large, the tests may take a few hours.
