[Lazarus] Selection block/brace

[Vojtěch Čihák]

Hi,
 
I tried two items from Lazarus Edit menu: Select to Brace and Select Code Block. Both seem do nothing. Are they broken? I didn't use them before so I expexted they would do what their name say. I have Lazarus 1.9.0 r57693M FPC 3.1.1 x86_64-linux-qt.
 
Thanks
