# Modifying Sequences

Let's go back to the main window now.

Once you have defined a sequence with `Pick`, you'll be able to use the `Add to Sequence` and `Remove from Sequence` commands to move messages into or out of the sequence.

To remove a message from a sequence, be sure that you're viewing the sequence in the Table of Contents (if you aren't, select that sequence on the menu, then select `Open Sequence`). Then, highlight the message(s) in the Table of Contents and use `Remove from Sequence`. This doesn't delete the message! It just takes the message out of the sequence. If you remove all the messages from a sequence, the sequence is deleted.

To add a message to a sequence:

1. Find a sequence that the message is in now (usually, `all`). View that sequence in the Table of Contents.
2. Select the message(s) in the viewed sequence by highlighting them.
3. Select the destination sequence (the sequence you want to add the messages to) with the first mouse button.

   The accelerator uses the third mouse button instead of the first. It selects the sequence and adds the selected message(s) to it -- if you do that, skip step 4.

4. At this point, your window might look like the Figure below; we're adding message 8, from the displayed sequence `all`, into the `mailquestions` sequence. Notice that the check mark in the `Sequence` menu is next to the selected sequence `mailquestions`. Use the `Add to Sequence` command.
5. If you want to open the selected sequence (here, `mailquestions`), choose `Open Sequence`.
