Any way to highlight matching characters with different case?

[SoftCircuits]

Is it possible to do either of the following?

1. The code correctly detects when the entered text matches the start of an item even when the case is different. But it only bolds the matching characters in the list when they match case. Is there any way to bold the matching characters even when their case does not match?

2. When the user presses the up or down key, the input control is populated with one of the items from the list. Is there any way to highlight the list item in this case?
