Busybox is a single utility that contains the functionality of many of the basic Unix tools. It's used on most embedded-Linux systems instead of having separate executables for each utility, which wastes space owing to code duplication.
There are several Busybox installers available on Google Play, and one on F-Droid. Custom ROMs often have Busybox built-in....
A programming editor might solve your issue. Take a look at e.g. 920 Text Editor or DroidEdit:
920 Text Editor and DroidEdit (Source: Google Play; click images for larger variants)
Both support at least syntax highlighting for several programming languages, and from the screenshot at least DroidEdit seems to be able to directly work with Dropbox (see the ...
You can easily create a plain text file in Android which can be opened by editors like Notepad, Wordpad, Gedit, Kate, etc. in PC. I use 920 text editor (hasn't been updated since ages) for such and use them in Kate editor of KDE Plasma in Slackware GNU/Linux (Also tested in Windows and Ubuntu). You may use any other editor of your choice. See this answer or ...

Vi (or, its line-editor predecessors ed and ex) is always in-built with Unix and Unix-based systems.
If its not available in your device by default, install busybox (rooted device is required). Busybox bundles vi editor, too.
For anyone who comes across this via a search I found these options...
Polaris Office's word processing program implements undo that works via control-Z on my Galaxy Note 3 using a Bluetooth keyboard.
The JotterPad X text editor implements undo and redo that works fine via on-screen controls.
The JotterPad X app description on the Google Play store claims ...
One way is to use another app to manage your dropbox that enables this functionality. I use Astro File Manager to generally manage the files on my device and this can also link directly to your Dropbox, Google Drive, SkyDrive, etc.
Astro gives you the additional option to "Open As", from which you can choose Text, Audio, Image or Video. Select "Text" and ...
Android 4.2.2 already contains the advanced copy/cut/paste functions. Calling it up is intuitive too - just long press on a word, then use the field edge indicator gadgets to select the text you want to cut.
Then on top you will see some icons representing specific functions. There will be a copy one (Number 4 in the image above), a paste one (Number 5), ...
One way to do this would be rooting the device, to obtain the "Mms.apk", and manually reverse-engineering it (using tools like apktool), and finding the overlay that's showing the text edit area's size (and the step that naturally follows, increasing it :) )
Not all requirements of the question are met in this answer, but this is as close as I got so far, and I'm quite happy with it.
So, this requires to copy the telephone number without the contact name, like this:
+370 666 11111
Next, I used tasker to create a task which reads the number from the clipboard, loses the "+370" and spaces and then adds ...
I'm not sure if there is anything like AutoHotKey in Android but it is possible to get the timestamp in that format for the current time on demand.
You'd need Tasker or any other app which can run a command.
Setup a task with these actions:
Code → Run Shell:
Command: date "+%Y%m%d%H%M%S"
Store Output In: %date
System → Set Clipboard → ...
No AFAICT, unless it it is preinstalled by the device manufacturer, for example some devices like Xiaomi, Huawei come with a preinstalled document editor (WPS), which not allows you to view but to edit text files as well.
As suggested above, stock android only comes with with text viewer , not editor, in any case if you need to install it, please see Izzy's ...
Simpletask does what you ask for. It creates a new line in a todo.txt file.
Personally, I use Simpletask Cloudless and sync with syncthing. There is also Simpletask Nextcloud and Simpletask Dropbox. And if you like it, we should donate to the author (just found this amazing solution two days ago, so I didn't do it yet).
For what it's worth, here are the solutions I've found so far, but I'm happy with none:
DroidEdit has an SFTP/FTP option in the pro (paid) version. I have not tested it myself so I can't guarantee anything.
I used to mount a samba or NFS share on my local Android file system, using the CifsManager app, which can be tunneled through SSH, and then you work ...
What is your Android version?
When you highlight the text, just click the highlighted text to copy it.
Then you can paste it by long clicking on a text input field.
On Android 3+ the system changed, and you now copy and paste using the bar that appears when you long press on some text.
A new version of Microsoft's OneNote is out on Android (tablets only I'm afraid), which I think you can do exactly what you want. Type a text and handwrite over it. Here's a blog post describing the features.
I think that the best results are obtain with a Note tablet though, with an actual pressure sensitive electronic pen.
Jota Text Editor: a small program, not like the huge office suites.
I have tested it and seems to be working: I created a .rtf file from Jota on Android, sent to a Windows PC, and Wordpad opened it OK.
Issue detected: seems not to open (at least correctly) .rtf files created on Windows by using Wordpad (if someone knows how to correct it, please report)...
On Android, the best rtf Editor I have found sofar is OfficeSuite, which I use in conjunction with FolderSync, in case no WiFi is available, I can then edit the rtf on the lokal drive of the tablet and then sync with whatever cloud drive you are using.
