1) I'm working with a Grid, and in a Column I put a ComboBox. Now I want (when selected) to insert my own text in the ComboBox (this text I want to go to Base1.table1) and if I select text from the list (with a click in the list button) this text will go to Base1.table1 too (but the text on the list is from Base2.table2).
All work OK (the list contain rows of Base2) but when type my own text in the Box it's cleaned. HOW TO DO??? I try in many ways... but nothing happened.

Data example of my case:
Column: ControlSource =Base1.table1
Bound to=F
ReadOnly=F
ComboBox: ControlSource =Base1.table1
Bound to=F
RowSource=Base2.table2
RowSourceType=Fields
ReadOnly=F

1.1) How to show the list of a ComboBox with the keyboard, not with a click in the button ???
1.2) There is a way to select controls from a Grid faster than selecting it from the PEM window ???
