Alot is an experimental terminal MUA based on notmuch mail. It is written in python using the urwid toolkit.

Have a look at the user manual for installation notes, advanced usage, customization and hacking guides.

Do comment on the code or file issues! You can talk to me in #notmuch@freenode.

• async. calls to mimeparts renderer, parsing of VT colour escape sequences. see #272. Milestone 0.4
• live search results while you're typing (POC in postponed-livesearch). Milestone 0.6
• search for message (POC in postponed-messagesmode). Milestone 0.6
• search for strings in displayed buffer. MS 0.7
• undo for commands. Milestone 0.7

The arrow keys, page-up/down, j, k and Space can be used to move the focus. Escape cancels prompts and Enter selects. Hit : at any time and type in commands to the prompt.

The interface shows one buffer at a time, you can use Tab and Shift-Tab to switch between them, close the current buffer with d and list them all with ;.

The buffer type or mode (displayed at the bottom left) determines which prompt commands are available. Usage information on any command can be listed by typing help YOURCOMMAND to the prompt; The key bindings for the current mode are listed upon pressing ?. See the manual for more usage info.
