Cursor

The cursor of the editor shows the position where the user currently inputs data. The cursor has four positions:

• preceding the operation
• inside the symbol string
• following the last operation
• preceding the operation symbol 

When the cursor is in the position "preceding the operation," the insertion occurs before the operation. The cursor looks like a vertical line preceding the operation and a dashed line underlining the operation.

Examples:

In this case, the cursor is in the position preceding the division operation (position "preceding the operation"):

The position "preceding the symbol" is characterized by it limiting the graphical presentation of the operation. The insertion is impossible, but the deletion is possible - the operation is deleted, but its parameters remain intact.

Examples:

Here, the cursor is in the position before the root symbol.

In cases in which the cursor is in the "inside the line" position, editing of the symbol line is performed (number or string input). The cursor becomes a vertical line, pointing the position for a new symbol input and underlining the edit line.

Examples:

The position of the cursor is in the number.

When the cursor is in the position "following the last operation," the insertion occurs behind the last operation. The cursor looks like a vertical line behind the operation and a dashed horizontal line underlining the operation.

Examples:

Here the cursor is in the position after the last formula item.
