DL no longer available. Download link and developer site redirect to MacKeeper ads and dating sites. Remove this crap Macupdate, or host binaries yourself please.

Version 0.8

You're right the links are dead and point to some generic search site; however, I at least didn't get a Mackeeper page.

There are benefits to MU keeping these pages of old software, however:

1) For the historical record and

2) you can see what was available and may still be available elsewhere, i.e. do a search on:

keycastr 0.8 soft

and at least a couple of pertinent sites show up. I have acquired software in this way a number of times.


I tired Googling and couldn't find the .dmg. It's not out there. Please post a link if you have one.

To be honest, I would prefer not to have useless remnants of no-longer-available software on download sites. It makes searching for particular functionality that much harder when something that does the job appears to be available but ultimately is not. What use is this to anybody? Do you want Macupdate to be an empty link farm for dead apps?


Google (keycastr dmg) is your friend.

I'm really enjoy KeyCastr.

However, i found that it didn't display the "words(my typing)" in my Mac and even i'm maximum the front size.
Then, i changed "Selected visualizer" into ""Svelte". i found that it only can detect the "Command", "alt", "shift" and "control" buttons in the bottom of "box" which display nothing at "large area" in box whatever i type.

Could any one help me?Thank you!!!

Got the same Problem, but it works now!
How did I do it?

Go to you System Preferences, and then click on that "human in the blue circle" 4 row 1 Object. (Sorry I don´t know the name of it english. Anyway it deals with disabled People)

And now enable the second checkbox from the bottom!
It is called: "Enable access for assistive devices option."

That´s it!
Hope that helps, and leave a comment!

Pretty cool app. Some small feature suggestions:

- Ability to display command keys only - many times in graphics software one holds down command keys to temporarily swap tools. Would be nice to be able to display these.

- The bezel doesn't grow proportionally to the font size at the larger font sizes (displayed text ends up on two lines)

- Option for text abbreviations instead of Command Key symbols (i.e. Cmd, Ctrl, Opt, Esc, Tab, Ret, etc.). Some people have no idea what those symbols mean :)

Regardless, cool little app!

Oh, and add an option in the Dock menu to start/stop KeyCastr (for those who don't want to use the menubar item).

Hi there!

* Ability to display command keys only
I assume you mean "display just the meta key when it's being held down". KeyCastr has this ability, but the default visualizer doesn't make use of it. If you switch the visualizer (use the Display panel in the preferences) to the Svelte visualizer, you'll note that the meta keys light up when they're selected.

* The bezel doesn't grow proportionally
Yeah, that's ugly. I'm planning to fix that.

* Option for text abbreviations instead of symbols
Great idea, thanks!

* Dock menu items for start/stop visualizing
D'oh! I'd meant to add that already. Good catch!

Thanks for your feedback!


Thanks for the quick follow up! I did notice that the Svelte style had a cool way of displaying the 'meta' keys, but is there a possibility to get at least resizing for it? On a larger monitor, it would be tiny on a the user's end when viewing via Ustream etc.

Sounds great on the rest, thanks!


Also: Svelte doesn't float above all other windows. And in addition to resizing, an option to use the bold version of the font? It's pretty waif-ish as is :)


The standard display does not remember a custom location for the Bezel if you relaunch or switch the display styles either.

Would be nice to have more control over the appearance of the default style, such as keeping it on screen while setting prefs, and being able to set the max size it grows to by dragging.

Svelte is nice, but very limited in comparison to the Standard display.

Stephen Deken (Developer)

Wow, really great feedback, thanks!

* Allow Svelte to resize
Seems reasonable to me, I can do that.

* Svelte doesn't float above all other windows
That's a bug, I'll fix it up.

* Svelte font is too light (use bold)
Also reasonable. Ideally I'd like to lighten the background when the meta keys aren't being held down, but didn't get there.

* Display location is lost when switching between visualizers
That's a bug. Thanks!

* Some easier way to keep the default visualizer on screen while setting prefs
0.7.x forced KeyCastr to have at least one bezel on the screen while the preferences window was open, but it was really buggy. I might be able to do it more cleanly with the new codebase, though. When you drag the bezel around, it won't fade away, but that's not helpful for when you want to see how the font size and so forth looks. Good suggestion.

* Max size of default visualizer
Also good. I'll think about how I could do that.

* Svelte is limited compared to the standard display
Svelte is really a rush job; it's only true purpose is to let you know that KeyCastr can support more than one style of display and can be extended with plugins. That's one of the reasons it has no preferences :)

I started KeyCastr and got a "Catastropic error" because the service wasn't running. Tried again and it started, but there was no Dock icon or menubar icon - I had to go to the Terminal to kill it.

This isn't some 10.5.2-related problem, maybe?

Hopefully once I've got to an icon, I'll be able to set a preference to only show keystrokes with a modifier key pressed.

It also seemed to be very difficult to move the window - it kept trying to jump back. The secret seems to be to keep pressing keys so the window doesn't try to close mid-drag...

Disregard the previous post. The secret to make the app work, is to enable access for assistive devices under the Universal Access Pane of System Preferences.

This app is great! It does exactly What I wanted.
In combination with iShowU or Snapz Pro, you can make great video tutorials.

oops!. got to clarify that the intel build of OSX is 10.4.9 not 10.4.8

so it doesn't work under 10.4.10 PPC
and it doesn't work under 10.4.9 Intel

I love this program so much. I helps my video tutorials on Photoshop and Blender. There is just a couple of things I think KeyCastr needs.
First - Much bigger fonts. Compressing my tutorials is hard when the keystrokes are not recognizable in the video.
Second - An option to record the command space with a Icon instead of a little squarish u
Contact me if u have any questions

Could you please tell me which version of 10.4 were you using when you tried this software?

Will this show individual letters, as opposed to just key combinations? For example, were I to type the letters W-H-A-T-D-O-Y-O-U-M-E-A-N-1-2-0-0-0-0-D-I-A-R-I-E-S -A-R-E-G-O-N-E-B-E-C-A-U-S-E-Y-O-U-D-O-N-T-K-E-E-P -B-A-C-K-U-P-S", would the individual letters display on the screen as they were typed?

Exactly how sharp do you need to make that ax, Mike?

Yes, it will show individual letters as you type them. Please see the screencast on the KeyCastr homepage:
