With HBX you are no longer limited to launch only 4 applications with the four hard buttons of your PDA.
Now pressing each hard button pops up a window with a choice of 4 previously selected applications.
You can also assign 4 programs to the Calculator silk screen icon, and one per Up, Down and Center buttons.
Furthermore, each Graffiti character (letter, number, etc.) or keyboard key may be assigned to one program.
All these features make Hard Button Extender (HBX) much faster tool than any launcher or similar program!
