Any key on a standard Windows keyboard can be assigned, including letters, numbers, Enter, and Spacebar, providing full replacement functionality. Supports one-key combination shortcuts (pressing multiple keys simultaneously), allowing any combination of Ctrl, Shift, Win, or Alt with other single keys, e.g., Ctrl+C, Ctrl+Alt+A. Uncommon keys such as F13 to F24, absent on standard keyboards, can be assigned and recognised by the computer. Multimedia keys including volume control, track navigation, play/pause, mute, and calculator functions can be configured. Mouse functions can be set to simulate left, middle, or right mouse clicks only. No additional keys can be assigned. Total macro space: 34 bits. Each pair of brackets in the configuration software counts as 1 bit. Total special key space: 10 bits. Each pair of brackets containing one, two, three, or four of the following counts as 1 bit: Ctrl, Shift, Win, Alt. The maximum delay is 10 units, configurable from 0.1 to 25 seconds, executed sequentially after delay. Exceeding any limit prevents further configuration. The 34-bit capacity represents shared memory for the entire keyboard, not dedicated to any single key. Each pair of brackets constitutes one step; steps are independent. Once pressed, keys must be released immediately; they cannot remain pressed while awaiting other key presses. Both single-key actions (e.g., delay 1 second + A) and shortcut keys (e.g., Ctrl+C) count as one step, each occupying one bit of macro space. However, shortcut keys additionally occupy one bit of special key space, while delays occupy one bit. Macros cannot incorporate mouse actions. Long presses trigger continuous macro execution; during loops, other keys remain inactive and cannot trigger actions. Example: (A) + (1-second delay + 2) + (Shift+F8) + (Alt+Win+R) constitutes a 4-bit macro, with 2 bits for special keys and 1 bit for delay (maximum 10).
