Editing KiCAD keyboard PCB design guide (section)

=== Placing components footprints ===
Import all the components defined in the Eeschema schematic editor by clicking the ''Read netlist'' button in the top toolbar. This ends you up with all components nicely stacked on top of each other. Spend some time shuffling everything out to get some overview. The more keyboard oriented way of sorting out the mess is to use the shortcut ''t'' which let you pick up a component by specifying its reference. Next place some switch in a tactical integer coordinate location. Have the grid set to inches - keyboards are standardized in them, and the KiCAD internal representation is in inches anyway. Landing '''Esc''' on (0,0) can be a good idea for example. Continue placing all the switches correctly spaced. The c-c distance of two single unit wide keys should be 0.75". Setting the custom grid to 0.1875" is very helpful. The c-c distance between any two switches should be the average of their individual width, the distance between a 1.25u and a 6.25u key would be 0.75"x(1.25+6.25)/2. This quickly gets messy - make yourself a spreadsheet of all switch locations you intend to use. It would be great if the grid could be set to 0.75"/8=0.09375". Unfortunately this is below the preset 1/10000" tolerance. The bottom line of this is that you need to enter some of the switch locations by accessing the edit menu of the component, and enter the coordinates manually.
