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.

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 colour.

When you have finished typing, press Escape. That leaves the editor without deleting anything, and lets you Tab to the box's own controls.
Step 3: Move the Box
Tab to the box's drag grip, then use the arrow keys.
- 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, 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.
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.
All the Keys

| Drag grip | Delete or Backspace | Remove the box |
| Resize handle | Arrow key | Resize by 5 pixels |

Once everything is where you want it, download the PDF with your changes to keep them.
