Wrong behaviour when shift-clicking on a line number
Instead of the entire intervening text between the insertion point—or the current selection—and the line whose number is clicked or tapped on in the gutter while holding down shift, only that particular line is selected. The app actually tries to do the right thing at first, but then it glitches and selects just the one line.

Character count
When using Textastic for blog or social media posts in markdown it would be really helpful to be able to get a character count of selected text.

Support using Alt as Meta key in SSH terminal
In the macOS terminal, enabling the "Use Option as Meta key" option allows using a number of shortcuts to edit a command. For example, you can press Option + F to move forward by a word, Option + B to move back by a word, Option + Delete to delete a word and so on. There's no option in Textastic's SSH terminal to use Option as Meta key. instead, for example, pressing Option + F enters ƒ rather than moving forward by a word; ditto for other Option shortcuts.
The ask is for Textastic to offer a setting that will enable using Option as Meta key in the SSH terminal.

Additional keys cover part of the UI unless full size keyboard is enabled
When using the floating keyboard on iPad (the one that doesn’t cover 50% of your screen) the additional keys row covers all UI elements and input on the bottom of the screen which makes the app effectively unusable.

Support for IDL (Interactive Data) language
I would like to have support for the coloring syntax of this programming language (Interactive data Language) distributed by NV5 geospatial (file *.pro). Is it possible to include it in future version of the APP?

Use a-Shell app as an external debug console
You should collaborate with a-Shell app to use it as an external debug console.
a-Shell is an amazing environment that simulates the same shell of the Mac(Darwin) on iPad / iPhone and let the user run and debug all interpreted languages (because Apple forbids apps to compile binaries). But for javascript, wasm, Python, etc. a-Shell behaves exactly like a shell, running code in Javascript, wasm, Nodejs, Python, etc and debug it. But a-Shell lacks a visual text editor, and Textastic could be its perfect companion.
It just need the following features:
- a button to immediately run/debug a python script in a-Shell (a-Shell allows to select and unlock writing/reading permissions on any iCloud Drive or iPad folder), opening a-Shell and running a dynamically generated bash script to run the python code with arguments.
- specify multiple launch properties when debugging/running the code, generating a bash script to open in the source file folder with a-Shell (for example first clean the file with Black, then run it with the parameters specified in the launch properties config). Multiple launch configurations should be stored for each file.
- Using the bash script passed to a-Shell, give the option to save the console error output in a error.log file with a date that can be opened or kept open by Textastic.
- On iPad there should be the amazing option to run a-Shell window and the Textastic window side by side! Coding and instantly see the script running!
Please, consider this!

Add an AI assistant, would make it a lot more fun to Code.
Maybe add an AI that you can ask Questions about Code, that would make the App more beginner friendly and would make Code more understandable.

Markdown "Format" option
Alexander,
I do all my writing using Markdown. This often involves reviewing documents and needing to 'highlight" text.
I know that I can do this by inserting "<mark>selected text</mark> from the Textastic additional menu bar. This, however, is fiddly and time consuming when there is a lot of text to be highlighted.
As an alternative, would it be possible to add a "Highlight" option to the "Format" menu option when text is selected. This would insert "<mark>selected text</mark>" around the selected text.
This option would be a considerable productivity enhancer if it could be done.
Regards,
Peter Anderson

Kotlin Syntax Highlighting
Textastic is a fantastic code editor. However, I’d like to be able to work on some of my android projects on the go using an iPad. TextAston doesn’t do anything for Kotlin (.kt) files. Would really love to see support for this in the future – would be extremely helpful since there are not really any options for android development on iPad at the moment. Thanks for all the work you’ve already put into this insanely great app!
