FontCreator already has a number of keyboard shortcuts (or hotkeys), but many frequently used features do not have keyboard shortcuts currently built into the program. FontCreator Hotkeys (FCHK) more than doubles the number of hotkeys available to the program, and modifies some of the preexisting hotkeys for easier use or for compatibility with the newly created shortcuts.
FCHK is a script wrapped into an executable (.exe) file. It is not a program, and it does not install on your system. As such, the files need to be stored on your computer or on a USB stick in a safe place. It is recommended to create a folder called FCHK in the user directory C:\Users\[User]\ (replace [User] with your username), or on your Desktop, and to unzip the contents of FCHK.zip into it. When downloading updates, replace the files in that directory with the updated files.
Please note: FCHK and its developer are not associated with High‑Logic B.V. or with AutoHotkey Foundation LLC.
