Switching between PDF documents
Master PDF Editor can open multiple PDF documents at once and allows you to switch between them.
All open documents display as tabs above the view area.
Click a tab to switch between open documents.
Thumbnails
You can use page thumbnails to quickly move to the required page.
To display the thumbnails of pages, click the Pages tab 
in the Navigation Panel.
This will open the side panel with thumbnails of pages. Scroll through the panel to find a page you need, then click its thumbnail to get to it.
For a better experience, you can change the size of thumbnails and the Navigation Panel. Right click a thumbnail and choose Enlarge Page Thumbnails or Reduce Page Thumbnails in the context menu.
If you remove, copy, or move a thumbnail, the same action is applied to the corresponding page.
Page navigation
To navigate through pages of the document, use the View > Go To menu, the View toolbar, or keyboard shortcuts.
- To go one page down, press PgDown.
- To go one page up, press PgUp.
- To go to the first page, press Home.
- To go to the last page, press End.
If you know the exact page number you want to go to, type the number in the box on the View toolbar, then press Enter to go to that page:
View navigation
Views in Master PDF Editor are specific states of the view area that you can switch back and forth. A close analogy is Back and Forward buttons in a browser. When you click Back in your browser, you return to the previous page you viewed. The same way you can return to previous views in the open PDF document. This tool effectively allows you to quickly navigate through specific pages, search results, and various parts of the document without navigating to them directly again and again.
- To switch to the previous view, use the View > Go To > Previous View menu command, or click the Previous View toolbar button
. - To switch to the next view, use the View > Go To > Next View menu command, or click the Next View toolbar button
.
Searching in the PDF document
There are two ways in Master PDF Editor you can search through the PDF document:
- Use the search box on the toolbar.
- Use the Search side panel.
Toolbar search box
To make a search using the toolbar box, type any keyword into the search box on the toolbar, then press Enter.
To find the next occurrence of the keyword, press F3.
Clicking the down arrow of the drop-down box brings up the search settings.
- Case Sensitive. Search for the keyword taking into account the exact case of symbols.
- Include Comments. Search for the keyword in both the text of the document and the comments.
- Whole Words Only. Search for the keyword as a whole word only, not a part of other words.
Search panel
To open the search panel, click the Search tab on the side panel 
or press Ctrl+F. This will open the side panel. Type the keyword in the search box and press Enter.
In the search results list below you will see all fragments of text containing the specified keyword. Clicking a result opens the corresponding page of the PDF document and the keyword is highlighted.
You can adjust the search preferences below the search box.
- Case Sensitive. Search for the keyword taking into account the exact case of symbols.
- Include Comments. Search for the keyword in both the text of the document and the comments.
- Whole Words Only. Search for the keyword as a whole word only, not a part of other words.
Navigating using bookmarks
You can use bookmarks to go to specific locations in the document. Bookmarks are displayed as a tree in the Navigation Panel.
To navigate the document using bookmarks, click the Bookmarks tab 
on the left side panel. Then choose the bookmark you want to navigate to. You can expand its content with the Expand icon 
, or minimize it with the Collapse icon 
.
Navigating to a bookmark not only restores the saved location in the document, but also the zoom level.
Apart from going to the required destination in the document, you can perform the following actions using bookmarks: open another file, a web link, reset forms, show or hide forms, submit forms, launch a JavaScript.
Please refer to the Managing bookmarks section to learn how you can add, delete, and modify bookmarks.
