By far the most common type of recognition error in MoboMath is substituting one character for a very similar one – for example, z for 2, 1 for I, or x for X. The easiest way to fix a character substitution error is to tap the incorrect character to replace it with an alternate recognition result. You can tap repeatedly until the character cycles back to the original recognition result.
This is the simplest and most useful example of getting alternate recognitions. You can also select a subexpression and then tap it to get more possibilities for the that part of the expression.
If you tap on a bracket, both elements of the bracket pair will switch to an alternate form.
If you have a selection (either a single character or a larger subexpression) you can use the Edit menu to get alternate recognitions. The "Next alternate" menu item is equivalent to tapping the selection. The "List alternates ..." menu item presents all the possible alternates in a list like the one shown below, and you can select the alternate you want. This list shows alternates for one example of the character 2:
Troubleshooting
If you tap a character and nothing happens but the dot goes away, it means that MoboMath couldn't find a good alternate. There are a couple of things to consider in this case:
| • | Does MoboMath support the character you are writing, or have you disabled that character? Check if you're not sure. |
| • | If a character you write is frequently recognized incorrectly, you may want to use adaptation to tell MoboMath how you write this character. |
If you tap and nothing happens and the dot does not go away, be sure to use undo to erase the dot before trying again. This usually happens when you accidentally tap between characters, or accidentally make the dot too big.
