Keymappings and Presentation Remotes

[roblem]

My presentation remote (Kensington Wireless Presenter with Laser Pointer) works flawlessly going forward or backwards through slides, correctly advancing through slide and sub-slide sections.

The problem is with the laser button (which is also designed to start a presentation in powerpoint): hitting that sends F5 (key 71) which reloads the webpage and kicks the presentation back into notebook mode.

I have tried disabling keys in main.js (in ~/.ipython/nbextensions/livereveal) at around line 180, to bind key 71 to NULL:

71: null, // F5 disabled on kensington (added)

However, I believe the browser intercepts F5 and executes a page reload and overrides any keyboard settings in main.js.

But F5 is 116... not 71... can you try disabling 116?
If it does not work, I guess this could be an option: http://stackoverflow.com/questions/2482059/disable-f5-and-browser-refresh-using-javascript

Thanks Damian,

Despite xev reporting key 71 as F5, disabling F5 using code 116 as you suggest works. So adding the following line to the keyboard section of main.js solves my problem and allows me to use the laser pointer without exiting the slideshow:

116: null, // F5 disabled

As an aside, the stop button on the remote sends b. Pressing this button or pressing b on the keyboard when in presentation mode continues to insert an ipython codecell when in livereveal, even with it disabled in main.js. Since I never use this feature of the remote anyway, it isn't a big deal.

Nice to know it is working...

Can you open an issue for this? ^^^

Thanks! Closing this one now...
