The following describes an implementation manner of the key mapping matrix switching of the electronic device with reference to a specific example:
as shown in fig. 1, the electronic device may be a computer, and certainly may also be any electronic device having a keyboard and a certain processing capability, such as a PDA, and the like, at this time, the keyboard is a virtual keyboard, for example, a pressing operation of a key is realized in a touch manner, and a key value corresponding to the key is triggered, for example, coordinates of a user approaching or/and contacting a screen are detected through a touch screen, a key corresponding to the coordinate value is determined according to the coordinate value, and a corresponding key value is triggered. The computer body can be a notebook computer or a desktop computer; the attached figures take the first key in the keyboard of the notebook computer as the Ctrl key for explanation;
the computer includes: a keyboard having a plurality of keys; and
the storage module is used for storing a first version key mapping matrix and a second version key mapping matrix corresponding to the plurality of keys in the keyboard; wherein,
wherein a first key (e.g., Ctrl key) of the plurality of keys corresponds to a first key value (e.g., a key value that implements a Ctrl function) in the first version key location mapping matrix, the first key corresponds to a second key value (e.g., a key value that implements an Fn function) in the second version key location mapping matrix, and the first key value is different from the second key value; of course, if the first key is an Fn key, the first key corresponds to a first key value in the first version key location mapping matrix (e.g., a key value for implementing an Fn function), and the first key corresponds to a second key value in the second version key location mapping matrix (e.g., a key value for implementing a Ctrl function);
the obtaining module is used for obtaining a switching instruction;
and the processing module is used for switching the first version key mapping matrix into the second version key mapping matrix according to the switching instruction.
In the above embodiment, if the first key corresponds to the first key value in the first version mapping matrix, the second key corresponds to the second key value in the second version mapping matrix; a second key in the plurality of keys of the keyboard corresponds to the third key value in a first version mapping matrix and corresponds to a fourth key value in a second version mapping matrix; if the first key value is the same as the fourth key value, the second key value is the same as the third key value; the first key and the second key just realize function exchange;
if the Ctrl key of the notebook computer is the first key, the Fn key is the second key;
the first key value of the Ctrl key in the first version key position mapping matrix is the key value of the Ctrl function,
a second key value of the Ctrl in the second version key position mapping matrix is a key value of the Fn function;
similarly, the third key value of Fn key in the first version key mapping matrix is the key value of Fn function,
a fourth key value of the Fn key in the second version key position mapping matrix is a key value of the Ctrl function;
the key value of the Fn function of the Fn key in the first version key position mapping matrix is the same as the key value of the Fn function of the Ctrl key in the second version key position mapping matrix, and the original functions of the Fn key are realized;
similarly, the key value of the Ctrl function of the Ctrl key in the first version key location mapping matrix is the same as the key value of the Ctrl function of the Fn key in the second version key location mapping matrix, which both implements the original function of the Ctrl key;
thus, the function exchange of the Ctrl key and the Fn key is realized just after the first version key mapping matrix is switched to the second version key mapping matrix, and the user who is used to the Fn key at the leftmost side of the keyboard can be switched to the first version key mapping matrix or the second version key mapping matrix; for users who are used to Ctrl keys on the leftmost side of the keyboard, the key mapping matrix of the second version or the key mapping matrix of the first version can be switched to, and the use requirements of the users are met.

Correspondingly, in order to make the reloaded key position mapping matrix consistent with characters printed on each key on the keyboard, the Fn key of the keyboard is also provided with Ctrl marks, and the Ctrl key is also provided with Fn marks;
the keyboard further has an indicator light for indicating whether the current selection is the first version key mapping matrix or the second version key mapping matrix.

the patch with the Fn characters is applied to the first version key mapping matrix at the position of the Fn key in the keyboard or the second version key mapping matrix at the position of the Fn key in the keyboard;
the adhesive film with the Ctrl characters is attached to the first version key position mapping matrix at the position of the Ctrl key in the keyboard or the second version key position mapping matrix at the position of the Ctrl key in the keyboard.
In addition, in order to enable a user to more conveniently identify the currently enabled key mapping matrix, keyboard lights can be arranged under the keys, for example, icons of Ctrl and Fn are engraved in a hollow manner on the first key, a plurality of keyboard lights are arranged under the first key, and when it is detected that the user uses the first version key mapping matrix, the keyboard lights of the part under the first key corresponding to Ctrl are lightened; and when detecting that the user uses the second version key mapping matrix, lightening a keyboard lamp of a part corresponding to Fn below the first key.

6. The method of claim 5, wherein the step of obtaining a handover command comprises:
obtaining a starting instruction set by a BIOS, and entering a BIOS system setting menu according to the starting instruction;
and obtaining the switching instruction according to the second version key mapping matrix to be started selected from the BIOS system setting menu.
7. The method of claim 5, wherein the step of obtaining a handover command comprises:
obtaining a calling instruction of an interrupt program in the operating state of an operating system of the electronic equipment, and starting the interrupt program according to the calling instruction;
and obtaining the switching instruction according to the second version key mapping matrix to be started selected from a setting interface generated after the interrupt program is started.
8. The method of claim 7, wherein the step of initiating the interrupt routine further comprises:
pausing the operating system and saving a first state of the operating system when paused;
the step of switching the first version key mapping matrix to the second version key mapping matrix according to the switching instruction comprises:
and saving the setting of the key mapping matrix of the second version, ending the interrupt program and restoring the operating system to the first state.
