Edit

Edit the current read only text.

View

View the current file read only.

Save

Save the current file if modified.

Open

Choose a file to open from the chooser dialog that pops up. The parent folder will be the first in the list. See File Chooser. The file will initially be read-only. Touch the Edit toolbar item to enable editing.

Open recent

Choose a file from the list that pops up. As above the file will initially be read only.

Save as

Enter a new file name in the dialog that pops up. Absolute names starting with a slash '/' will be saved in that exact path. Names without a starting slash will be saved relative to the main public folder, /sdcard/, or /storage/emulated/0/.

Search

Enter search text in the field that pops up in the toolbar. The first matching item will be highlighted. Use the search button in the keyboard for find next. The exact regular expression syntax used is in the android documentation for Pattern.

View markdown

You will be prompted to choose a viewer for an html file containing the encoded markdown from the current open file. If the text contains no markdown the result will be the same text.

Highlight syntax

If the current open file is a C, C++, Objective C, Go, Java, Javascript, Python, Shell script, Swift, CSS, HTML or Markdown file, the keywords, classes comments, strings, etc will be highlighted. See Syntax Highlighting.

Mode line

If a line of text is found within the first or last two or three lines of the file which matches the mode line pattern, the mode of the editor will be changed after the file is loaded. See Mode line.

# ed: [[no]vw] [[no]ww] [[no]sg] [[no]hs] [th:l|d|r] [ts:l|m|s] [tf:m|p]

Extended selection

If the file being edited is not a plain text file, selections created by double tapping or long touching on the text will be extended to enclosing delimiters (brackets, quotes) on the same text line.

Unsaved file

If you touch the back or open button, and the current file has been modified, you will be prompted whether you want to save it, else the editor will just exit or open a file chooser. The current file may be saved on app pause using the menu option. The scroll position and name will be remembered for the last 10 files opened.

Changed file

If a file has changed in storage while it was open in the editor, if you attempt to save it, or the app is resumed, you will be prompted whether to overwrite or reload the file.

Default file

If there is no open file any text entered will by default be saved in Documents/Editor.txt. This file will be loaded on start if it exists. Use the Save as menu item to save it elsewhere.

Shared file

Text files opened or shared by another app may be viewed and edited. Some apps may share files or text using a content URI that is not resolvable to a path to a file in storage. In that case the editor will read the file into the default file. The default file in storage will not be overwritten unless the file is saved. Use the Save as menu item to save the file elsewhere.
