In Photoshop Elements 5, the hidden functions are patched automatically during "Animated Intro" installation. In other versions, you run "Show_Tools.exe" patch. After restarting Photoshop Elements you can find 6 new functions in your "Effects" palette (screenshot »).

With the older PSE versions, run "Show_Tools.exe" file (coming to you with the full-versioned video-book). After restarting Elements, in the "Styles and Effects" / "Effects" palette, there appear 10 new functions (animations below).

The patch unlocks most features that matters to photographers:

- Soft Proof enables you to preview how your image will be processed by the target output device (for example, by your desktop printer)
*This function works in any Photoshop Elements version.

- 4 masking commands enabling creating, editing and
handling "regular" layer masks (PSE naturally supports only adjustment layer masks.)
*These functions work in any Photoshop Elements version.

- the missing selection commands - Transform Selection* and Color Range.**.
*This function works in any Photoshop Elements version.
**These function only works in Photoshop Elements 3.

- the missing adjustment commands - Color Balance, Selective Color, Curves and Channel Mixer.
