You see work in progress here; this section already reflects future TED Notepad version 5.4.1.1.
This section may contain incomplete, premature, or mistaken information, prone to change without notice.

The meaning of some terms used in this manual is as follows below:


  • A white-space is a Space or a Tab or another character that can not be seen but provides blank visual separator in the document. All other characters which can be seen, are called graphs.
  • An alphanum is an alpha-numeric character, i.e. a, b, ..., z; A, B, ..., Z; 0, 1, ..., 9.
    • Special characters like á (a with acute) belong to alphanums only in certain locale settings. To be able to recognize these characters as alphanums you need to use CTYPE category of a locale that supports it. TED Notepad always works with the current system locale settings.
  • A capital is any capital letter, i.e. A, B, ..., Z. These are called letters in upper letter case or simply upper case letters. Their oposites are called lower case letters and are in lower letter case or simply in lower case.
    • Special characters like á (a with acute) belong to capitals only in certain locale settings. To be able to recognize these characters as capitals you need to use CTYPE category of a locale that supports it. TED Notepad always works with the current system locale settings.



  • A word is a non-empty sequence of alphanums. Underscores may be optionally included** within words and a phrase hello_world is then also treated as a single word within all Tools and Functions. All characters that such a word can consist of are called word letters or also word characters. Other characters are considered to be word delimiters
  • A line is a sequence of characters, where two lines are divided by a CR/NL sequence of characters. Note, that if Word Wrap is turned on, a line may be wrapped, but within all tools it will be still treated as a single line. Also note, that a single NL or CR character does not divide two lines.
  • A sentence is a sequence of characters that begins with a capital and ends with a Dot, a Question mark or an Exclamation mark. Example: Alice? Who the f... is Alice? are two sentences, but Alice? Who the f... Is Alice? are three sentences. Unfortunatelly, even How are you today, Mr. President? are two sentences, which is not very fortunate.
  • A char range is a sub-sequence of characters that begins and ends at the specified positions. Char range is used to cut out a sub-string from a longer column.
  • An actual insertion point (also called a cursor position) is a position of the caret in the documnet or the end of the actual selection, if any. Note, that in special cases, it is the beginning of the selection, if any. These special cases are tools/features that work backward. (e.g. Find Previous or BkSpace Word.)
  • To unique lines is to remove duplicate lines, to unify them. If lines or words are uniqued, it means that each line (word) is unique and there no two lines are of the same text.
