Text edit

You can add or replace text only if the font used for that text is installed on your system. If the font isn’t installed on your system but is embedded or subsetted in the PDF, you can make changes only to color, word spacing, character spacing, baseline offset, or font size.

You can edit text on rotated lines in the same way as on horizontal lines, and you can edit text using vertical fonts in the same way as text using horizontal fonts. The baseline offset or shift for vertical fonts is left and right, instead of up and down for horizontal fonts.

Edit text using the TouchUp Text tool
1) Choose Tools > Advanced Editing > TouchUp Text Tool, or select the TouchUp Text tool on the Advanced Editing toolbar.
2) Click in the text you want to edit. A bounding box outlines the selectable text.
Select the text you want to edit:

• Choose Edit > Select All to select all the text in the bounding box.
• Drag to select characters, spaces, words, or a line.

4) Edit the text by doing one of the following:

• Type new text to replace the selected text.
• Press Delete, or choose Edit > Delete to remove the text.
• Choose Edit > Copy to copy the selected text.
• Right-click/Control-click the text and choose the appropriate option. Click outside the selection to deselect it and start over.
