Currently, you can select a bank statement line and view the Match Details. There is no way to select a Bank Account Ledger Entry and view Match Details because whatever is selected on the bank statement line is what appears in the Match Details. There is no way to deselect a bank statement line and select just the bank account ledger entry.

Suggestion is to have the Match Details feature go both ways. Be able to select either a Bank Statement Line or a Bank Account Ledger Entry to view what it is matched to.
