The top toolbar has two general-purpose controls in the middle — a color swatch and a number input — that automatically switch to match whatever tool or element is currently active. Understanding how they connect makes day-to-day adjustments much smoother.
The color swatch: controls color
Clicking it opens a color picker — pick a preset or set any custom color. This one control serves several purposes: text color for added text, highlight color, drawn line color, and rectangle border color.
The number input: controls size or thickness
What this input means depends on the active tool:
- With the Text tool — it's font size (bigger number, bigger text)
- With Draw or Rectangle — it's line thickness
Two moments to adjust it
- Before adding: switch to a tool, set the color and size/thickness in the top toolbar first, then add content on the page — the new element uses that setting directly.
- After adding: use the Select tool to click an existing element, and the top toolbar automatically shows that element's current color and size/thickness — change it directly and it updates live, no need to delete and re-add.
A practical tip
If a document needs several annotations in the same style (say, all problems flagged in red highlight), set the color once before adding them all in a row — much faster than adding each one and going back to fix the color afterward.
Try adjusting color and size to build your own annotation style.
