SetFocus Shortcuts to switch between fields easily

[Webmaster]

I have 4 fields on form.  I would like to enable the shortcut ./ entrys
common in other palm apps to make it easy to switch between fields.
what are the character constants for these shortcuts (forward 1 field /
back one field) and what is the best way to jump between fields?
currently i use: FrmSetFocus(frmP, FrmGetObjectIndex(frmP, FieldID)); 

thanks
