The toolbar above the editor formats the side or step you’re writing. Each of its buttons shows its shortcut when you point at it.
Formatting
You can use bold, italic, strikethrough, inline code, bulleted and numbered lists, code blocks and links. Headings, tables and quotes aren’t available on cards. Each side or step can hold up to 10,000 characters.
The shortcuts, with ⌘ in place of Ctrl on a Mac:
- Bold: Ctrl B
- Italic: Ctrl I
- Strikethrough: Ctrl Shift S
- Code: Ctrl E
- Bulleted list: Ctrl Shift 8
- Numbered list: Ctrl Shift 7
- Code block: Ctrl Alt C
- Gap, on cloze cards: Ctrl Shift C
Math and chemistry
Type a formula between dollar signs, such as $x^2$, and it turns into math as you type. Type $$
on an empty line for a formula on its own line. Formulas are written in LaTeX, the notation most
math and science courses use, and chemistry works too, for example $\ce{H2O}$.
Click a formula, or press Enter on it, to open the math panel. It shows the LaTeX with a live preview, has a palette of symbols, and puts the formula in the line or on its own.
A dollar sign only starts math when no space follows it, so “costs $5 or $10” stays text. To write
a dollar sign that never starts math, type \$.
Gaps on cloze cards
Select the words to hide and choose the gap button, or use its shortcut from the list above. With the cursor in a gap, the Hint field next to the toolbar sets a hint shown in its place while you study.
Steps
On a steps card, Enter or Add step adds the next step, and Backspace in an empty step or its × removes it. Drag a step by its number to move it, or focus its number and use the arrow keys.
Images
Add an image to the side you’re writing with the image button, by pasting it, or by dropping it on that side, which says so while you drag. Images can be up to 10 MB. Image occlusion cards work a little differently, see Image occlusion cards.
Dropping a file anywhere else on the editor adds it as a source instead. See Cite sources on cards.
