Unless you send coins, nothing happens, even if the squares are "ticked" or not.
If you want to consolidate your blocks, or send the least mature coins, you would do this.
Go to setting/options/display and check "display coin control features", then close that window
Click send coins, click the "Inputs" tab, check "list mode". This will show you all the blocks,size, and their age. The oldest ones are the ones with the most confirmations.
Mark whichever blocks you want to send,move or consolidate, then click "OK" to close that window.
You will be back at the "send coins" tab, and the coins you send will be those that were previously selected. In the upper portion of the wallet, it will show "Amount after fee". You can copy this, and paste it to send. You can send them all to yourself, or wherever you want, and they will end up as one large block, rather than a bunch of tiny blocks.
Keep in mind, after sending they will need 24 hours to mature again. You also have to pay the transaction fee of 0.00001.
Let me know if I missed something, or if anything is unclear.
