*aerc-config*(5) for details on configuring outgoing emails.
*filter* [options] <terms...>
Similar to *search*, but filters the displayed messages to only the search
results. See the documentation for *search* for more details.
*mkdir* <name>
Creates a new folder for this account and changes to that folder.
*next-folder* <n>, *prev-folder* <n>
Cycles to the next (or previous) folder shown in the sidebar, repeated n
times (default: 1).
*next* <n>[%], *prev-message* <n>[%]
Selects the next (or previous) message in the message list. If specified as
a percentage, the percentage is applied to the number of messages shown on
screen and the cursor advances that far.
*next-folder* <n>, *prev-folder* <n>
Cycles to the next (or previous) folder shown in the sidebar, repeated n
times (default: 1).
*next-result*, *prev-result*
Selects the next or previous search result.
*search* [-ru] <terms...>
Searches the current folder for <terms>. Each separate term is searched
case-insensitively among subject lines.
*-r*: Search for read messages
*-u*: Search for unread messages
*select* <n>
Selects the nth message in the message list (and scrolls it into view if
necessary).
