Psion Teklogix 7535 Hand-Held Computer Quick Start Guide 31
The <SHIFT>, <CTRL> and <ALT> keys operate much like a desk-
top keyboard except that they are not chorded (two keys held down
simultaneously). The modifier key must be pressed first followed by
the key whose function you want modified.
Activating Modifier Keys
When a modifier key is pressed once, it is displayed in lowercase let-
ters in the taskbar at the bottom of the 7535 screen. For example, if
the <CTRL> key is pressed, ctrl key is displayed at the bottom of the
unit screen. Once the next key is pressed, the modifier key becomes
inactive and disappears from the taskbar.
Locking Modifier Keys
When a modifier key is pressed twice, it is ‘locked’ on. A ‘locked’
modifier key is displayed in uppercase letters in the taskbar. For
example, pressing the <BLUE> key twice locks it on – it is dis-
played as BLUE KEY in the taskbar at the bottom of the computer screen.
The locked modifier key will remain active until it is pressed a third
time to unlock or turn it off.
2.3.2 The Keys
The <SHIFT> Key

up, down, left and right.
