Jotter:

The Jotter is a quick place to capture the things worth keeping - an idea, someone you have just spoken to, a podcast, a useful fact - and find them again later. Open it from the title-bar notebook button or its right-edge tab.

• Open the Jotter Draw by clicking on it, or pressing the Jotter button in the title bar or by pressing Ctrl + J
• Type a descriptive line and press Enter, then add free-text notes and any tags you like. Find things again by searching (the line, the notes and the tags all match) or by clicking a tag to see everything labelled that way. The ⤢ button opens a wide reading view for longer notes. Everything here is personal to you, and its tags are kept separate from your To Do tags.
