// * **Mod-b** for toggling [strong](#schema-basic.StrongMark)
|
|
// * **Mod-i** for toggling [emphasis](#schema-basic.EmMark)
|
|
// * **Mod-`** for toggling [code font](#schema-basic.CodeMark)
|
|
// * **Ctrl-Shift-0** for making the current textblock a paragraph
|
|
// * **Ctrl-Shift-1** to **Ctrl-Shift-Digit6** for making the current
|
|
// textblock a heading of the corresponding level
|
|
// * **Ctrl-Shift-Backslash** to make the current textblock a code block
|
|
// * **Ctrl-Shift-8** to wrap the selection in an ordered list
|
|
// * **Ctrl-Shift-9** to wrap the selection in a bullet list
|
|
// * **Ctrl->** to wrap the selection in a block quote
|
|
// * **Enter** to split a non-empty textblock in a list item while at
|
|
// the same time splitting the list item
|
|
// * **Mod-Enter** to insert a hard break
|
|
// * **Mod-_** to insert a horizontal rule
|
|
// * **Backspace** to undo an input rule
|
|
// * **Alt-ArrowUp** to `joinUp`
|

// * **Alt-ArrowDown** to `joinDown`
|
|
// * **Mod-BracketLeft** to `lift`
|

// * **Escape** to `selectParentNode`
