Memorize efficiently with the masking pen function

The masking pen function helps you efficiently memorize desired parts of documents or notes by covering them up.

Flexcil's masking pen feature goes beyond simply covering documents; it allows you to check correctness and measure accuracy.

You can activate the masking pen in the pen options.

After tapping the + icon in the pen toolbar, select the masking pen by clicking the rightmost icon, then press the  button at the bottom to add the masking pen to the pen toolbar.

Alternatively, if the pen icon is already active, you can select the masking pen icon after tapping the pen icon once more to change the registered pen to a masking pen.

Using the Masking Pen to Cover Documents

You can use the masking pen to cover the content of documents. To cover the content of a document, simply activate the masking pen and draw a line over the area you want to cover, just like using a pen.

Using the Gesture Pen

For documents with text recognition, you can easily select and neatly cover text using the gesture pen.

To use the gesture pen, make sure the icon in the pen toolbar is in the state on the far left.

If the icon is not displayed as shown above, please tap it once more to change it to the state.

In gesture mode, select the text and then tap the masking pen in the popup that appears.

Using the Straight Line Pen Option

When the masking pen is active, you can tap the masking pen icon once more to access pen options. In the pen options, activate the "Straight line" option to draw the masking pen neatly.

Using Long Touch

When using the masking pen and keeping the pen pressed without releasing it, it will automatically transform into a straight line. This allows you to draw straight lines conveniently.

Precautions

1. If you use the masking pen in a location where other objects such as handwriting, highlighter, or text have been input, the masking pen will always be positioned on top.
2. While the masking pen is active, you cannot use the shape correction tool.
3. When exporting a document, the masking pen is not included.
4. When synchronizing and backing up data, the masking pen is also included, ensuring that the data is preserved.

Masking Pen Annotations During Recording

Annotations made with the masking pen during recording are also synchronized, and masking pen annotations are played back along with voice data.

Disabling the Masking Pen

To disable the masking pen, simply touch the location where the masking pen has been drawn with a pen.

When disabling the masking pen, you can choose whether you answered correctly or incorrectly, allowing you to check whether you memorized the document correctly.

Checking and Measuring Correct and Incorrect Answers

You can check the accuracy of your answers, both correct and incorrect, in the side menu.

Tap the icon in the upper right corner of the document viewer to open the side menu.

In the menu tab, tap the rightmost tab to open the annotation tab.

In the annotation tab, you can review all annotations, including those made with the masking pen.

Select "Masking" at the bottom of the annotation tab to view only the content marked with the masking pen and check the correctness rate as well as the number of attempts and correct answers.

※ When using the correct/incorrect feature in split-screen mode, the last touched screen will be used as the reference for correctness/incorrectness.

Masking Annotation Sorting

You can use the sorting filter located in the upper right corner of the masking tab to sort annotations made with the masking pen by page order or correctness rate.

Deleting the Masking Pen

Deleting with the Eraser Tool

Tap the eraser icon in the pen toolbar, then touch the masking pen object to delete it.

※ If you want to delete only the masking pen in a document with multiple objects, activate the eraser tool, tap it once more to reveal the eraser filter, and then activate the masking pen option.

Deleting with the Eraser Gesture

Switch to gesture mode and draw zigzags over the masking pen to easily delete it.

※ Eraser gestures do not apply to the eraser filter. Therefore, when using the eraser gesture, all objects within the gesture area will be deleted.

Deleting with the Page Eraser

The page eraser is a feature that allows you to delete all objects within a specific page.

You can delete all masking pens on an individual page with a single touch, and if there are other objects such as handwriting or highlighter on the page, you can activate only the masking pen option in the eraser filter and then use the page eraser.

The eraser filter can be accessed by tapping the eraser icon when the eraser tool is active.

Deleting with the Lasso Tool

You can also use the lasso tool to select and delete objects. If there are other objects on the page, such as handwriting or highlighter, you can activate only the masking pen option in the lasso filter and then use the lasso tool to select and delete the masking pen.

With the lasso tool, you can not only delete objects but also move and copy them.

※ Objects input with gestures as masking pens cannot be selected and deleted with the lasso tool.

Deleting with the "Clear all annotations" Button in the Side Menu

Tap the icon in the upper right corner of the document viewer to open the side menu.

In the menu tab, tap the rightmost tab to open the annotation tab.

At the bottom of the annotation tab, tap the "Delete All Handwriting and Annotations" button to delete the masking pen.

※ Tapping the "Clear all annotations" button will delete not only the masking pen but also other annotations such as handwriting, text, and images, and it cannot be undone.
