Hi folks today I'm annotating and editing PDF files with the help of a mikvah Macworld article by Christopher Breen from August 1st 2013 so some of the things I've already learned from this article or how to and merge two PDFs and how I did that was I opened my finder and opened the got a thumbnail of the second PDF I wanted to add and I clicked on it and just dragged it over to right where I wanted to add it but I've already done this so I'm not going to do it now so what I did let's say I want to be on page 7 I am so I included the second PDF right after page 2 and what these PDFs are their emails instruction by Kirk Weiler he's created some great online materials for algebra and we use this in my classroom so I'm teaching two lessons so I wanted to put the notes for the second lesson right after the notes for the first lesson so as I'm going through the lessons I can note right on top of the worksheet so as I'm going through I'll be able to highlight this markup tool and I can use a pen whoops okay now it's making lines let's see want to be able to write ten hello see hello turn it it you can turn it into a lion or an arrow or I can keep my hello I can also write text let me move that text box okay the answer is I can delete that by going highlighting it and clicking edit delete let's delete this edit delete and I like this edit too late okay not only can I write or type within the field but I can highlight and I did that on page oh let's try that again don't need to find her anymore it was on page seven so let's use our thumbnails page seven okay so there's a highlighter right here you can select your color I chose green I highlighted and then what I did is I right clicked oops right click and let's remove the note and let's right-click again and add a note okay there we go Iqra is inter quartile or time range so now there's a note is hatched and you can also add notes by clicking the notes button right here and remember that the nearest tenth means there will only be one number after the decimal and if I click away from that I can yes I want to highlight got to turn off my highlighter button now I can move that note right next to the tenth or turn the highlighter back on since is the yellow note let's yellow highlight right-click add note okay so I could do it just like that or I could do a the sticky note so one number number after the decimal place so there's a whole lot you can.
