The Frequently Used category contains operations that you frequently add to keyword tests. It provides quick access to operations that you use in your tests more often.
The category contains only those operations that you added to your tests manually in the Keyword Test editor. Recorded operations are not taken into account.
By default, the category is hidden. It becomes visible if you have added at least one operation to your tests on the current computer.
The operation use counter is shared among test projects that you edited on the current computer. If you open your project on another machine, the category can have other contents or it can be hidden.
