in excel what does the f1 key on the keyboard do?
help
the lists of modifier mappings is maintained by the x server but can be changed by every client. for example, a client can request the "f1 key" to be added to the list of "shift" modifiers. from this point on, this key behaves like another shift modifier. however, the keycode corresponding to f1 is still generated when this key is pressed. as a result, f1 operates as it did before (for example, a help window may be opened when it is pressed), but also operates like the shift key (pressing "a" in a text editor while f1 is down adds "a" to the current text).

the anykey uses rubber dome type keyswitches, with all the switches and contact points on a single sheet. the keyswitch layer contacts a single flexible membrane that detects all keypresses and directs them to the controller board via a pair of flexible edge connectors. while the anykey is branded as a gateway product, the membrane layer clearly bears the inscription “maxi switch inc,” revealing the true maker of the hardware. this membrane is backed by a metal plate approximately a sixteenth of an inch thick which serves to hold the membrane rigid and in place as well as giving the keyboard considerable heft. held in place on top of the rubber dome layer is a plastic block that holds the key pillars which in turn hold the keycaps themselves. the key pillars are individually replaceable but cannot be removed without dismantling the keyboard to separate the rubber dome layer from the plastic support layer and the removal of the latter from the assembly. the key caps are held onto the pillars via friction with cross shaped pegs. the key caps are easily removed for cleaning or rearrangement, as all keys on the keyboard use the same attachment method and, with the exception of the space bar, enter, shift, tab, control, alt, and caps lock keys, they are all the same size. in this manner, keys that have been remapped (like the commonly remapped arrow keys) can also be physically moved to the correct location on the board. physical relocation of keytops should be done with caution as the slope of the keytops is raked into three pairs of rows, e.g. if the z key is swapped with the f1 key, both keys will have different rake to those surrounding them.
