How to save keyboard shortcuts in Photoshop

Edit > Keyboard Shortcuts

Click one of the little “download” icons…

Left = Save As
Right = Save a Copy

This will place a file where you want it. Saving to the desktop is the easiest place.

Now merely drag that .kys file onto the Photoshop application icon. Photoshop will ask you if you want to save the current key configuration… and then apply the .kys settings.

Alternatively, you may be able to navigate to hdd/users/[you]/Library/Application Support/Adobe/Adobe Photoshop (version)/Presets/Keyboard Shortcuts and copy the .kys files there and then place them in the same location after a reinstall.

In fact, I will generally just copy the entire Presets folder and then replace it after a reinstall. Or copy it from a previous backup.
