This is a known problem with the syntax highlighter. See http://feedback.textasticapp.com/feedback/7433-syntax-highlighting-is-sometimes-wrong-with-strings-quotes-quotation-marks/

Sorry, but this is an annoying bug in a regular expression but I can't fix easily without rewriting a lot of the highlighter.
Textastic expects the key file to be in the format used by the OpenSSH utility "ssh-keygen".

You can convert your ppk file to OpenSSH format using puttygen. According to the article at http://leadingedgescripts.co.uk/server-administration/how-to-convert-your-putty-ppk-private-key-to-a-normal-ssh-key-you-can-use-on-an-apple-mac/ you have to do this:

"Now if you already have a .ppk file from your PC that you want to convert to use on your Mac you need to visit the Putty Website www.chiark.greenend.org.uk/~sgtatham/putty/download.html and download puttygen.exe (on your PC) now open it, and using the File menu, load your .ppk that you already use, and type in your pass phrase.

Now go to the Conversions menu and export the key as an OpenSSH key – hey presto – you now have a key file that will work on your Mac! Such a simple solution, yet that took me so long to figure out …"


I hope this helps.

I've added an entry to the manual: http://www.textasticapp.com/manual/lessons/Which_keyboard_shortcuts_can_I_use_with_an_external_hardware_keyboard.html

Unfortunately, it's not possible to add custom shortcuts like Cmd + > due to restrictions of iOS.
PowerShell support will be added in Textastic 2.2.
Great, thanks a lot for your efforts. I've added the syntax definition with some minor edits to Textastic. I had to move the autocompleteWords to keywords because Textastic doesn't highlight the autocompleteWords. It will be included in the next update.

The only problem is that the escape rules of PowerShell are not honored. But that's something I can't fix easily right now.

Here's a screenshot of the syntax definition in action:

You can use Cmd+A to select all text. Also, Cmd+C copies text and Cmd+V pastes text. These are standard iOS shortcuts.

You can select text using Shift and the cursor keys.

I found an article that lists some more iPad keyboard shortcuts: http://gigaom.com/apple/ipad-keyboard-shortcuts/



Here is the image for reference.
Looking forward to the screenshot(s).
