Editing Stabiliser (section)

===Guide shaft===
Some manufacturers such as Alps and Fujitsu used guide shafts for some or all large keys. A plastic insert is fitted, bearing a guide shaft, and a plastic post within the keycap fits into this shaft. This approach is not always successful; the Fujitsu FKB4700 is infamous for the poor quality of its stabilisation. However, this approach works well in IBM Model M keyboards.
