Prepare a plain text file containing sentences that you want to learn. Here is a sample file.
The first line and each line with a preceding blank line are treated as valid sentences.
If a sentence contains newline, each line should end with a backslash "\" except the last line.
Drag & drop your file to the application page.
You can set the number of blanks. 0 means to show the original sentence. If you want to change the blank number of the current sentence, click "again" button after you change the number.
Press Ctrl+Enter while the cursor is in a blank or click "check" button to check your answer.
Pressing Tab key to move to the next blank. Press Shift+Tab to move to the last one.
When the cursor is not in a blank, press →/← to go to the next/previous sentence.
When the cursor is not in a blank, press ↑/↓ to add/reduce a blank and refresh. Press Enter to refresh without changing the number of blanks.
