Program a Space Bar to Backspace
For added convenience, the Comfort Keyboard System allows you to program either the left or right space bar to backspace. Program Rest Period Indicator
Many ergonomists recommend that you stop for "micro-pauses" (brief, several-second pauses) frequently. Your keyboard will help you remember to take breaks periodically. 

Programmable "delay until repeat"
The "delay until" value is the time that elapses between pressing the first key and the insertion of the first auto repeat character.

Programmable "repeat rate" value
The "repeat rate" value is the rate at which a key repeats itself when held down. "Delay until repeat" governs the first repetition; "repeat rate" governs later repetitions.

Remapping
The "Remapping" mode allows you to re-map your keyboard (reassign keys to different key locations). This can be useful for software applications that require the repeated use of one or more specific keys; it is also useful for users who simply find it more convenient to have various keys rearranged.

Individually programmable macro keys "macro"
A macro is multiple keystrokes stored in a single key. Pressing that key plays back those multiple keystrokes. If you find yourself typing a particular series of characters repeatedly, you can program that series into a macro key. You simply select a key to represent the series of characters. You may also program macros to reassign (re-map) keys on your keyboard. In addition, you can use a macro to exit a program and enter another program quickly.

StickyKeys
Some people find it difficult or even impossible to press two keys down at the same time because they type with just a single finger or with a stick attached to their head or hand. If you want to operate your Comfort Keyboard System pressing one key at a time, use the StickyKeys function. It allows you to press each key separately when performing a multiple key operation.

Programmable BounceKeys
If you accidentally "bounce" on a key when you press it - that is, press a key and then accidentally press it again right away - use the BounceKeys function.
BounceKeys tells the computer that, if the user presses the same key two consecutive times, "don't accept the second press unless a certain amount of time elapses between them".
If you want to type the same key twice, just pause between the two key presses for the period of time (called the "debounce time") that you have programmed into BounceKeys. BounceKeys does not prevent you from typing other keys as quickly as you wish.

Programmable SlowKeys
If you accidentally "bump" keys while you are moving your hand or typing stick toward the key you want, "SlowKeys" will tell the computer not to accept keys that are bumped or held down for a very short period of time. In other words, using Programmable SlowKeys, the computer will accept a key as "passed" unless it's held down for the period of time (called the "acceptance delay") that you have programmed into SlowKeys. You can bump any number of keys on your way to the key you want without accidentally entering those characters. You can then hold the desired key long enough for the computer to accept it.
