Quick start
The Math Ribbon
Explore the commands in the Math
ribbon to get started with Calcumber Math Journal.
 | The Math Line button defines the selected paragraph for math input and output. Type your math followed by =. |
 | The Math Input button defines the selected paragraph as math input. Type your math and the output comes to a separate output paragraph. |
 | The Normal button converts back the selected paragraph to normal text. |
 | The Math Section button defines the selected paragraph as math section divider. The evaluation of each section starts with all variables cleared. |
 | Use the Start / Update Math button to start Math Journal or to manually update all math in the document if necessary. |

Hot Strings
Type the following at the beginning of a paragraph as shortcut:
| # | ➔ to normal text |
| :: | ➔ to single line math |
| == | ➔ to math input (output to separate paragraph) |
After some time of not editing math, hotstrings stop working. Use a ribbon command to wake up Math Journal and activate hotstrings again.
You may also use words built-in shortcut (depends on locale) to apply Normal
paragraph style:
Ctrl + Shift + N ➔ to normal text
