Editing Xmodmap (section)

==Introduction to XKB==
'''XKB''' is a utility for modifying X server keymaps on a much larger scale compared to '''xmodmap'''. The utility allows ultimate functionality for one being able to write up as much as up to eight layers for keyboard bindings. The definition of keyboard bindings for instance is the case of:
* Pressing alphanumeric to input the desired character on the screen.
* Holding (or having Caps Lock) Shift key and pressing alphanumeric keys to attain either a set of characters with capitals as opposed to lowercase and/or to print a completely different character on the screen as per user's request.
* Holding Alt Gr (or better known as Dead grave) key along with pressing alphanumeric keys to print out specific characters of user's preference. Notable examples of these may be found on [[ISO| ISO]] keyboards but are not restricted to only ISO keyboards as the keyboard mapping are done on the software level.
* Holding both Shift and Alt Gr along with pressing alphanumeric keys to print out a potentially different set of characters based on user's preference. Again examples may be found on layouts that entails the need to use Alt Gr key to print out specific characters.

In addition to being able to map specific keys and their varied levels of printing certain characters on the screen (which is what '''xmodmap''' is practically capable of). '''XKB''' allows one to define how many layers should a keyboard layout have along with the amount of physical keys, etc. This is particularly handy for dealing with keyboards that have a fancy amount of keys and with one wanting to add many varied levels of character output however at the same time it adds more complexity to the issue.
