I assume the multiple messages you refer to are email messages.
If so, you can delete multiple messages as follows:
1. For messages listed one above the other in a row, use you mouse to select the first message so that is is highlighted. Then hold down your shift key and select the last message in your continuous list of messages. All the messages from the first to the last should now be highlighted (i.e., selected). While in this mode with the messages highlighted, press the delete key on your keyboard, or alternately, use your mouse and select the delete icon at the top of the email screen (it looks like a trash can).
You can also just drag the selected emails while holding the shift key down into your system trash.
2. For multiple messages that are not in a continuous list, while holding down the option key, use your mouse to highlight each message by clicking on it. When all the messages you wish to delete are selected, as above, press the delete key on your keyboard or use you mouse to select the delete button at the top of the email screen.

Release the Shift Key. And Delete.

2. To delete multiple messages that aren't in chronological order click on the first message you want to delete. The press and hold the Option Key (Windows Key if you have 3rd Party Keyboard) and select each message you want to delete and it will highlight all those messages individually. After you select all messages you want to delete let go of the Option Key and click on the Delete icon in the mail menu bar.

Important:
