Why Use the Keyboard?
Filling in a PDF usually means dragging a box to exactly the right spot on a line. That is fiddly with a mouse and hard for anyone who cannot hold a pointer steady.
Every part of a Helperbird text box can be done from the keyboard instead. You move it with the arrow keys, one pixel at a time if you need to, and resize it the same way.
Who is This For?
This is helpful for:
- Anyone filling in a form who needs the text to land on the line
- People with tremor, limited hand movement, or joint pain
- Screen reader and keyboard-only users
- Anyone who finds precise dragging slow or frustrating
Step 1: Add a Text Box
Open your PDF, then press Add Textbox in the toolbar.
View full-size image (opens in a new tab)A new box appears on the page. Each one you add is offset slightly from the last, so they do not stack on top of each other.
Step 2: Type Your Text
The box opens ready for typing. Type what you need, and use the formatting bar if you want to change the size, weight or color.

Step 3: Move the Box
Tab to the box's drag grip at the lower-left corner, then use the arrow keys. Focusing a box control reveals its toolbar again. The bar with the arrows icon also supports dragging with a pointer.
- Arrow key moves the box 1 pixel
- Shift + arrow key moves it 10 pixels
One pixel at a time is deliberately fine. It is what lets you sit text neatly on a form line rather than near it. Use Shift to cover distance, then tap the arrow keys on their own for the last few pixels.
Step 4: Resize the Box
Tab to the box's resize handle at the lower-right corner, then use the arrow keys.
- Arrow key resizes by 5 pixels
- Shift + arrow key resizes by 20 pixels
Make the box wider if your text is wrapping when you do not want it to, or narrower to fit a column.
To reduce the text size as well, see how to make PDF text boxes smaller, with screenshots of the size menu and corner handle. Boxes go down to about 160 pixels wide and one line tall.
Step 5: Delete the Box
With the drag grip focused, press Delete or Backspace. The box and its text are removed.
There is also a delete button on the box itself, which you can reach with Tab.
