In Writer, the Edit > Find functionality is by default assigned the Ctrl+F shortcut key combination. But it appears impossible to assign that to any other possible shortcut, because in the Tools > Customize > Keyboard dialog, the "Find" command is missing, i.e., not found under any of the categories.
Steps to Reproduce:
Look in Tools > Customize > Keyboard dialog for the "Find" command and see it is not shown under any of the categories.
The "Find" command missing.
The "Find" command present under the "All Commands" category and at least one other category.
User Profile Reset: Yes
Shown the command.
Assignment of Find to a shortcut other than hardcoded <Ctrl>+F or <Find> key requires wrapping into a UNO command, open as bug 80914
