Here’s a quick tip how to select multiple conversations with just two mouse clicks.
To check a range of conversations from the index, click the checkbox next to the first conversation then hold down the shift key while selecting the last conversation. If you are familiar with selecting a range of cells in a spreadsheet, this is very similar. Automatically, Gmail will highlight and select all the conversations from the first one to the last. Again, check the first conversation, hold down the shift key while selecting the last conversation. Instantly you’ll have 3, 12, or 20 conversations selected at once. You can do this repeatedly on the same screen if you have multiple ranges to select. Unfortunately I haven’t found a keyboard shortcut for this yet.
Once the conversations are selected you can label, archive, delete them, or any other regular action that you perform on one or more conversations.
