I also use BackPack for Notes. I like having it at work and at home.

I found Google Notebook and its associated Firefox extension an excellent tool in capturing notes/page fragments/links.

Here’s the original bookmarklet script:
(There’s no comment preview, so let’s hope this works…)

Note: all of this needs to be on a single line in the bookmark “Address” field; I’ve added line breaks and spacing for readability.


javascript:(
function(){
m='http://mail.google.com/mail/?view=cm&fs=1&tf=1&to=&su='
+encodeURIComponent(document.title)
+'&body='
+encodeURIComponent(document.location);
w=window.open(
m,'addwindow',
'status=no,toolbar=no,width=575,height=545,resizable=yes');
setTimeout(function(){w.focus();},%20250);
}
)();


We can remove the two references to the current page (that you were viewing when you clicked the bookmarklet) to create a blank form:


javascript:(
function(){
m='http://mail.google.com/mail/?view=cm&fs=1&tf=1&to=&su='
+encodeURIComponent(document.title)
+'&body='
+encodeURIComponent(document.location);
w=window.open(
m,'addwindow',
'status=no,toolbar=no,width=575,height=545,resizable=yes');
setTimeout(function(){w.focus();},%20250);
}
)();


On the third line (remember this all needs to be in one line in the Address field of the bookmark), add your email address immediately after “to=” (no spaces) and before “&su=” so that piece looks like this (replace [email-addr] with your address):


&to=[email-addr]&su=


You can also add “NOTE – ” (without quotes) immediately after “&su=” as Chris suggests and/or change the “width=” and “height=” values to fit your screen.

So:
1. Go to the About.com page and drag the bookmarklet to your Bookmark toolbar.
2. Copy that second code block (or copy the link location/URL from the bookmark you just added) and paste it into your text editor of choice
3. Remove the reference to “document.title”: +encodeURIComponent(document.title)
4. Remove the reference to “document.location”: +encodeURIComponent(document.location)
5. Add your email address between “to=” and “&su=”
6. Paste it back into the Location field of that bookmark(let) on your toolbar
7. (optional) I created a filter in Gmail for messages from me sent to me to add a label so I can find them easier

Hope this helps!
