Computer keyboard

A computer keyboard, comprising:

• a mechanical control key area, coupled to a host, having a plurality of mechanical control keys for transmitting a corresponding control signal to the host when one of the mechanical control keys is pressed;
• a plurality of function modules, wherein the function modules are timing modules, temperature sensing modules, or humidity sensing modules;
• and
• a touch control display panel, coupled to the host, comprising:
• a display unit, comprising a first display unit electrically connected to a display control unit and the host, for displaying icons of a plurality of control keys, text, or patterns, wherein a screen width of the first display unit is about once through twice a width of the mechanical control key;
• a second display unit, electrically connected to the display control unit and the function modules, for displaying measuring values outputted by the function modules;
• a plurality of touch sensing units, coupled to the host and arranged to the control keys, text, or patterns on the first display unit, for sensing pressed status of corresponding positions of the control keys, text, or patterns on the first display unit, and transmitting corresponding control signals to the host;
• and
• the display control unit, electrically connected to the first display unit and the host, for receiving the icons of the control keys, the text, or the patterns from the host, and making the first display unit display the icons of the control keys, the text, or the patterns;
• wherein when an external force presses one of the control keys, text, or patterns on the touch control display panel, a specific touch sensing unit senses pressed status of a position corresponding to the pressed control key, and makes the host start or terminate an executable program according to a link of the executable program corresponding to the pressed control key, where the link of the executable program corresponding to the pressed control key is a linking relation for a specific application program of a fast key on a desktop of a main display panel of a computer;
• when the fast key on the desktop is selected and dragged to edge of the main display panel, the host transmits a relate information of the fast key to the display unit, the display unit displays the dragged fast key on a predetermined position to realize switching display position of the fast key, wherein the relate information of the fast key comprises icon of the fast key and the linking relation for the specific application program of the fast key.
