Skim – An Alternative PDF Reader & Note Taker for Mac
This is a PDF reader and note-taker for OS X which was originally designed to help users read and annotate scientific papers in PDF. But it is also great for viewing any PDF document.
Focus On Readers
The first thing that I noticed from Skim was the unique features of the table of contents pane on the left. Chapters that I have read are marked differently to unread chapters. And if you hover your mouse above a specific part of the document, Skim will show a quick glance of the content. I think this is a very useful feature for doing quick skimming.
This table of contents pane also allows you to do a quick search on a specific word or phrase from the document. This feature will be very handy if you are dealing with a very thick text book with thousands of pages. You can choose to see the results by words or by relevance.
If you want to focus on your reading and free yourself from distraction, go to “View – Presentation (or Fullscreen)” menu.
Skim will show only the document with other things blocked out.
If you combine the feature with “Tools – Rotate” menu
Along with “PDF Display – Single Page” and “Zoom To Fit” under the “PDF” menu,
You could turn your MacBook into a nice eBook reader -athough holding a laptop sideways is a little bit uncomfortable.
Focus On Learners
Skim lets users create notes easily within the PDF document. So if you find something useful in the book or you want to be reminded about things that you need to do regarding the text that you read, just add some notes directly on the page.
There is another kind of note called “Anchored Note“. This type is used for longer notes. You can assign a title and icon to it. It resides on a page as a small icon and will pop up if you double click on it.
To further the ability to annotate documents, Skim also allows users to draw circles, rectangles, and lines; and also to highlight the text.
Another tool that can help users in their learning is taking snapshots. You can take “snapshots” of important sections of a PDF document, to keep them on your screen for easy reference. This way you don’t have to leaf back to the section every time you want to see it.
All of these annotations and snapshots could be found quickly by using Notes Pane. You can show/hide the pane via “View – Show/Hide Notes Pane“.
If you need to remove one (or more) of the notes, you can do so by right clicking on the item(s) within this pane and choose “Delete“. It’s possible to use other basic editing commands here such as Copy, Edit and Select. Choosing “Show” will bring you the notes from wherever you are in the document.
These are only a few basic features of Skim that I was able to explore during my short encounter with it, but it covers what ordinary users need. Power users might want to dig deeper to more advanced features such as AppleScript support; Interaction with LaTeX, SyncTeX, and PDFSync; and Integration with BibDesk and other third party applications.
