Type-searching for all listviews

[matortheeternal]

Description

Like windows explorer type to jump between files in a directory.

Implementation details

• If delay between two key press events is greater than a certain value (1 - 2 seconds), clear buffer and add that key to the beginning of the buffer
• If space is pressed as first character of buffer, process it as a "check this checkbox" input
• If we've just cleared the buffer, clear user selection and start searching at beginning of the list
• Only buffer [a-z][A-Z][0-9], space, and some filename-supported symbols
• Each time KeyPress event is detected, jump to next item in list (from selected item) that matches buffer
• If no item found matching buffer between currently selected item and end of list, leave selection on current item and make a beep
• Should be implemented as a decoupled method that takes a ListView and a BufferString
