A lot of people are complaining that the F1 function doesn't work. You have to go into 'System Preferences' and change your keyboard settings. Under 'Keyboard', make sure that you select 'Use all F1, F2 as standard function keys'. The automatic setting on these is such that you would have to press "fn" to use the F1 function normally.

Works like a charm! :)

As of 6-12-12 and Lion 10.7.4, this little app works, but it does have a few glitches from what I can tell:

- the "toggle on/toggle off" keyboard shortcut doesn't work, nor is it customizable/changeable. It says that it's Command-F1, but that doesn't work, and you can't change it.

- to get Highlight to stop being the active app, you need to hide it, via Command-H. Then you can change your screen, move to other apps, etc. Re-selecting Highlight as the active app will then again make it active.

So while a little rough on the edges, it does work. I use it when I'm using GoToMeeting and showing everyone something on my screen, whether it's PDFs, or my desktop, or Keynote/PowerPoint.

Thanks to the developer for making this. I'd be glad to pay some money for making it work a bit better.

the toggle off/on option by using command + F1 does not work on my mac. I see someone else had this problem. Can you please clarify?

thank you!

Command+F1 works all too well for me. I want a way to disable it.


I have this problem as well. Did you find the answer. I really want this app but I can't close boxes, only mark them up.


I have a problem as well: when I toggle on using Command + F1, my desktop shrinks to about half the screen in the middle of my iMac display and repeats itself on my second display. Everything gets back to normal when I toggle off. Useless app in this mode of operation.

I love this application.

One of the comments says it's possible to configure the keyboard command that activates and deactivates Highlight in the Styles panel. But I don't see any option to do that when I look there. The only parameters I can adjust are the line width and whether the tool tips are displayed. Am I missing something?

Very useful and appreciated for quick and easy markup of screen shots.

Adding lines with arrows would be helpful.

Thank you for making Highlight available.

The arrows are in version 1.5... :)

Gcoghill (developer)

From the documentation:

- Shift toggles the rectangle drawing tool
- Alt toggles the oval drawing tool
- Ctrl toggles the line drawing tool
- Ctrl+shift toggles the grid lines (vertical or horizontal only)
- Backspace removes the last shape
- Command K will clear all shapes
- A custom shortcut (set in the styles panel) will toggle the application on/off (system wide)

The arrow can be accessed via Control + Option


hey my friend,
i can't seem to inactivate the highlight using the the command button shows in pen styles "Command-F1" ....nothing happened

Please show me how to use it

Thanks for this small piece of software. It's great, and is helpful when you are sharing screens too. I am using to try to help my brother overseas (in Brazil) to configure a lot of things on the softwares that he is trying to install.

One small bug is when you open About.. then you are not able to close, because if so, you draw on the screen. I had to set some shortcut to disable the "pen" and close windows, etc.

But the author is really neat, responsive, polite, and I really appreciate. It's the best one in this category. I recommend. And want to see more updates, maybe some features to be easy to draw, like figures, shortcuts to "pens", etc. I am not good on ideas and creativity.

Please, keep going. You did a really good job. I could not do it! Thanks!

This another sreen draw program for Mac that won't draw on KeyNote presentations. As far as I can tell only Scribboard works with KeyNote. I would use Highlight if it worked on top of KeyNote presentations.

I have looked Scriboard up, and the readme says it works over Powerpoint (just like Highlight), but that's it.
Even Apple's own "transparent and above all apps" clock doesn't work on top of recent keynote presentations.
It used to work on top of Keynote 1.0 IIRC, but recent versions "capture" the display for their private use, preventing any other application from doing anything on screen during the presentation (probably because of potential ugly popups showing up)

Besides, I must stress that Highlight is free, and therefore not something I spend a lot of time working on. It's useful for me, and I hope it's useful for other people as well, but that's about it.

If you have special needs, send me an email, we can talk about it, but posting something like "it doesn't work as expected", when there are no fees, no promises and where I'm not necessarily aware of the user's feedback is just not useful.

Great tool, thanks! The option to safe as file is cool and the ovals and rectangles also. Just one option is missing: Typing text.
