Using the Keyboard
The Thomson Test Chart may be controlled using the keyboard.
The Primary Mode is selected using the function keys:
- (FI) LogMAR chart
- (F2) Snellen chart
- (F3) Single letter chart
- (F4) Duochrome test
- (F5) Fan and Block test
- (F6) Refraction targets
- (F7) Phoria tests
- (F8) Fixation disparity tests
- (F9) Fixation targets
- (FI0) Number plate test
- (FI1) Contrast sensitivity test
- (FI2) Polarised tests
The Secondary Modes and the various options available for each test are controlled by a variety of keys which are described in detail for each test. Wherever possible, keyboard keys are matched to the keys on the remote handset (e.g. I, U, M, R, O, L, Esc, PgUp, PgDn, Home, End, 1,2,3,4,5,6,7,8) and many functions can be selected by simply pressing the horizontal and vertical cursor control keys. The caption on the corresponding Toolbar button also provides a clue about the associated keyboard shortcut.
