Keyboard shortcuts

Every keyboard shortcut in Komorebi, from mail and the composer to tabs and windows.

In Komorebi, F1 or Ctrl+/ shows every key by group (also in Settings > About). This table is generated from the keyboard table in the project's README at the release this site was built from.

Key	Action
`Ctrl`+`N`	New mail
`F1` or `Ctrl`+`/`	Keyboard shortcuts: every key on this list, by group (also in Settings › About)
`Ctrl`+`,`	Settings, and back to the mail (as the gear and Settings' back arrow do; Esc closes them too; from the account form, Esc goes back to the list first)
`Ctrl`+`Enter` or `Alt`+`S`	Send (in the composer)
`Ctrl`+`Shift`+`C` / `Ctrl`+`Shift`+`B`	Show Cc and Bcc, and go to Cc / Bcc (in the composer)
`Ctrl`+`Shift`+`A`	Attach files (in the composer)
`Ctrl`+`V`	Attach the files copied in Explorer (in the composer; text pastes as usual)
`Up` / `Down`, `Enter` or `Tab`, `Esc`	Pick, take or close the recipient suggestions (while they show under an address field; a group adds each of its members)
`Enter` (in the contact editor's Name box)	Save the contact
`Ctrl`+`B` / `Ctrl`+`I` / `Ctrl`+`U`	Bold / italic / underline (in a formatted message's body, where Ctrl+U does not mark as unread)
`Ctrl`+`Shift`+`X`	Strikethrough (in a formatted message's body)
`Ctrl`+`K`	Link the selection to an address, or insert one at the caret (in a formatted message's body; Enter inserts, Esc cancels)
`Ctrl`+`Shift`+`8` / `Ctrl`+`Shift`+`7`	Bulleted / numbered list on the selected paragraphs (the key that types `8` / `7`); typing `-` , `*` or `1.` at a line start does the same
`Ctrl`+`Shift`+`Q`	Quote the selected paragraphs (again takes it off)
`Ctrl`+`L` / `Ctrl`+`E` / `Ctrl`+`R` / `Ctrl`+`J`	Align left / center / right / justify (in the body these come before Search and Reply)
`Ctrl`+`]` / `Ctrl`+`[`	One font size larger / smaller
`Ctrl`+`M` / `Ctrl`+`Shift`+`M`	Increase / decrease the indent
`Tab` / `Shift`+`Tab` (in a list or table)	A list item's level, or the next / previous table cell (Tab after the last cell leaves the table); elsewhere Tab moves the focus
`Ctrl`+`Space`	Clear formatting
`Ctrl`+`Z` / `Ctrl`+`Y`	Undo / redo text and formatting together (200 steps)
`Ctrl`+`Shift`+`V`	Paste as plain text (in the body, where it does not move messages)
`Esc`	Close the composer, saving the draft (in a composer tab, close the tab)
`Tab` / `Shift`+`Tab`	Next / previous control; the folders, the list, the reader's toolbar and the composer's formatting buttons are one stop each (a row's quick actions, shown on hover and on the keyboard's row, are never Tab stops: the keys below do the same)
`F6` / `Shift`+`F6`	Next / previous pane: the title bar's search, folders, message list, reader (toolbar, composer or the selection's buttons)
`Space` or `Enter`	Press the focused button or toggle
`Left` / `Right`	Move along the reader's toolbar or the formatting buttons (while they have the focus)
`Up` / `Down`, `Home` / `End`, `Enter` or `Space`	Move through the folders and open one (while they have the focus; Left / Right fold an account)
`Shift`+`F10` or `Menu`	In the folders: the row's menu (Mark all as read and Collapse all; on an account also Refresh and Account settings; on a rail tile its Inbox, Sent and Archive)
`Ctrl`+`R` / `Ctrl`+`Shift`+`R`	Reply / Reply all
`Ctrl`+`Shift`+`F`	Forward
`Ctrl`+`Shift`+`V`	Move to: the Move list with its filter box focused (type to narrow it, Enter moves to the first folder listed)
`Ctrl`+`Shift`+`I`	Go to the Inbox (All inboxes with two or more accounts; from Settings too)
`Ctrl`+`E`, `F3` or `Ctrl`+`F`	Search (the title bar's box; from Settings too, which then close)
`Ctrl`+`Q` / `Ctrl`+`U`	Mark as read / Mark as unread (Outlook's keys; on a selection, every message)
`Ctrl`+`S`	Save the message as a .eml file
`Insert` or `Ctrl`+`Shift`+`G`	Mark as important / Remove importance (Ctrl+Shift+G for keyboards without Insert)
`Backspace`	Archive (with the focus on a message row or the reader's page only; never in a text field, Drafts or the Outbox)
`Up` / `Down`	Previous / next message (with none open, the first); in Drafts, move to a draft (Enter opens it); in the Outbox, show the entry
`Home` / `End`	First / last message
`PageUp` / `PageDown`	Up / down by the rows the list shows
`Enter`	Open the selected message (with none, the first) and move to the page, where PageUp/PageDown, Space and Tab work
`Esc`	Close the folder pane opened over a narrow window (the toggle at the top of the narrow rail opens it), else clear the search, else the selection and the open message or Outbox entry (below 720 px, back to the list, as the reader's back arrow does), else "Select messages", else the status line (Esc on its buttons always closes it); never the Undo offer at the bottom of the list
`Ctrl`+`click` / `Shift`+`click`	Add or remove a message from the selection / select a range
`Shift`+`Up` / `Shift`+`Down`	Extend the selection
`Ctrl`+`A`	Select every message in the list (with the list focused)
`Delete`	Delete (move to Trash); in Trash (deleted on the server) or Junk, after asking (the prompt has no default button); in Drafts or the Outbox, discard the row (asking first)
`Shift`+`F10` or `Menu`	The row menu for what is selected, under the current row (a draft or Outbox row: Open, Discard)
`Ctrl`+`Z`	Undo the last archive, delete, move, junk report or send (while the offer at the bottom of the list shows: at least 10 s, or until the next one; its time stops while the pointer is over it)
`F5`	Refresh (also retries a rejected sign-in)
`Ctrl`+`Shift`+`E`	Show / hide the folders (the pane folds to the rail)
`Double-click`, `Shift`+`Enter`	Open the message in a new tab (a tab it already has comes forward)
`Middle-click`	On a message row, open it in a background tab; on a tab, close it
`Ctrl`+`O`	Open the message in a new window (a tab moved this way closes)
`Ctrl`+`W` or `Ctrl`+`F4`	Close the tab (not the Mail tab); in a message window, close the window
`Ctrl`+`Tab` / `Ctrl`+`Shift`+`Tab`, `Ctrl`+`PageDown` / `Ctrl`+`PageUp`	Next / previous tab
`Ctrl`+`1` to `Ctrl`+`8`, `Ctrl`+`9`	Go to tab 1 to 8, the last tab
`Ctrl`+`Shift`+`PageUp` / `Ctrl`+`Shift`+`PageDown`	Move the tab left / right (the Mail tab stays first)
`Ctrl`+`Shift`+`T`	Reopen the last closed tab
`Esc` (in a message window)	Close the window; in a message tab Esc never closes the tab

The keys that act on the selected message (reply, forward, read and unread, important, archive, Delete, Move, and the list keys above) work only while the reader shows, never in the composer or Settings. The list has the keys from the start, before any click. Show original has no key: it is in the reader's More menu (and the row menu), whose items show their keys.

On a message row, the quick actions (hover, or the keyboard's row) are Archive, Delete, Mark as important and Mark as read / unread: they act on that row only, never open it and never mark it read. "Select messages" in the list's "..." menu shows check boxes (a click then checks a row instead of opening it). A message opened from the Unread filter stays in the list, read, until the filter or the view changes (as in Outlook).
