This is just a super quick hack, not elegant, not clean, and I'm not sure where to post it.
For Background: It'd be nice to have an option for Portmonkey to not auto-fill in the stock name when the mouse passes by a tag, drove me nuts. Having as a checkbox in options would be great, but I'm not sure who to suggest that to.
In the meantime, go to greasemonkey, manage scripts, and edit portmonkey script. It should open in notepad, or whatever text editor you choose.
Go down to line 1351 (or search for "mouseover")
You will find this line:
item.addEventListener("mouseover", putTicker, false);
at the start of that line, comment it out by adding two slashes, so it looks like:
// --slashes stop this line from running-- item.addEventListener("mouseover", putTicker, false);
Save the .js file in the same place, and reload the page. SBL no longer auto-fills when your cursor goes over a tag. The bad news is, SBL doesn't fill out when you click on a tag, either, since that action is reserved for opening the security's detail page. So, to trade in the (no longer) Quick Trade pane, you need to paste the security, then pick amount and action.
That is a dirty hack that still leaves the infrastructure to add an "OnClick" method to fill out the SBL field, but for now, I'm happy enough copy pasta, since it isn't costing me half a million dollars in mis-clicks a day. I know some of you are better with a mouse and pay attention, but I lost too much, and the weekend is coming up, which means I'd be "erroring" a lot more...
If you have problems with it, just edit the file again and remove the slashes, leaving the original line 1351 intact. No need to reinstall.
This doesn't effect any of the other portmonkey functionality that I've found so far.
