This is a Text Editor mainly to read a text file with drag and pinch-in/out, and sometimes to edit it partially by operations in the left side drawer. This can lock the image of text.
This uses universalchardet, so can read almost character code. When you use file-managers with SMB access (like as Total Commander + LAN plug-in in content-scheme), you can edit files in NAS.
Long-Push around words, then the cursor comes there. And open the left side drawer, and choose a command, then you can edit or insert words.
Long-Push around a number of line, or Long-Push and drag, then lines are selected independent of the cursor. Then you can move or copy these lines in the text or to a clipboard.
