Arrow key functionality for iPad
The arrow keys on a bluetooth keyboard don't work when using writeLatex on iPad. This makes it much harder to use writeLatex for iPad and adding the functionality should make the experience much more pleasant.

It’s time to fix this — or time for me to cancel my membership. Bluetooth keyboard still wont work with Overleaf and iPad Pro.

They work if you use the iCab browser.

Is there an update on this subject? I am trying using my iPad using a BT keyboard and the problem has not been fixed yet.
i agree. we need this functionality and two way sync with dropbox asap

Exactly same problem here. Arrow keys won't work. Had to switch from iPad to Macbook because it's very hard to use overleaf with bluetooth keyboard.
This functionality should be, must be implemented immediately!!!!! Please resolve this problem first!!!!
I so want to have this feature! Without it writeLatex is useless on an iPad...
PLUS: if you have a longer source and want to scroll to the bottom of the file... that is VERY painfull since the scroll does not keep on rolling after my finger stops touching the screen... It takes me 90 seconds to reach the bottom of my document and I promise, I will never even try this again as long as nothing changes... ;)
@EM Thanks for taking the time to provide feedback -- that's very helpful.
I'm afraid that iPad support is a moving target, and some things that worked in the past may not be working so well now, such as Puffin, which worked great last time I tried it! We'll review this internally and try to improve again.
I'm sorry for the inconvenience that this is causing.

I echo the other's comments - it sure would be nice to latex on my ipad with the aid of my cursor keys!
It is shocking that you promote writelatex with its compatibility for ipad and iphone when it is clearly NOT compatible. I've enjoyed using the service on my mac and pc but It's bizarre that you don't at least change your promotion page to reflect the fact that it doesn't work correctly on an iPad.
Additionally John Lees-Miller, as an admin. How could you suggest another browser solves the problem, without at least testing it out?
I tried with CHROME and PUFFIN and they DONT WORK!
@Joe Thanks for the feedback. This is still on our list, and we have made some improvements on iOS, but I'm afraid we've not found any way around the problem with the arrow keys. It may work a bit better if you switch to a different mobile browser, such as Puffin (http://www.puffinbrowser.com), which behaves a bit more like a desktop browser. Let us know if it helps!
Any updates? WriteLatex is useless without this, and I'd really like to be able to use it!
Thank you very much for looking into this and for the link to editarea. We are working on a more mobile-friendly version of writeLaTeX, and we'll try out editarea to see whether it does what we need. I expect the main challenge will be getting the collaborative editing features to work in the new editor; we've got them working with other editors in the past, so we know it's possible, but it will take some time.
Thanks again, and stay tuned!

Can you look into it? It should only take a couple of hours and everybody who uses writelatex on mobile devices would benefit. Others using PCs will see no difference since this is working fine everywhere.
Please let me know what you think. It resolves all issues with CodeMirror, e.g. not only arrow keys but also copy & paste, and other.
Thanks for the feedback. We are still planning to do this; it's just a question of priorities and resources.
There are several open issues on CodeMirror related to this; there's a recent summary at
and if anyone would like to contribute high quality bug reports and patches, I'm sure that the whole CM community would appreciate it.
I have the same issue. It seems nobody in the writeLatex team is doing anything to fix it because they are not the originators of the problem. They have merely inherited it from whoever created the code editor.
Would it be possible to simply replace the code editor component? There are many other JS text editors that work fine on iPads. I definitely recommend the code editor to be replaced, unless of course the original authors can promptly fix the issue.
Did anybody contact them at all? What is the ETA?
Any progress? Without this, it makes it very hard to get any editing done.

Hey I'd like this functionality too, cause is really uncomfortable to navigate through text with the fingers while you're typing on the keyboard
Stephen Glazier commented
It would also be nice if the "tap and hold" text zoom feature worked... it is really hard to touch right in between letters. Thanks for looking into this.
Thanks for reporting this! It seems to be an issue with the code editor that we use. We're looking into how we can fix it, now. :)
