A Text Editor for Windows
Notepad2
If I suggested Editor² on the basis that it made it easier to add HTML tags to the content then Notepad2 is worth exploring because it has an excellent set of tools for edits to existing text that can be most useful if, for example, you want to copy content from a brochure created in a word processor or desktop publishing program. Layout that may work on paper often needs a lot of manipulation in order to get it to fit aesthetically on anything from a phone screen to a cinema room TV screen.
While its name may correctly suggest similarities with Windows Notepad, its name is about as far as it goes. Notepad2 adds a customisable toolbar and the menus drop down far further, providing a total of over 100 options to choose from and that's not counting the various settings on any dialogues opened on some of the options.
Here we see the Edit menu's "Block" option open. It is that and the four others in that section of the menu that provides the bulk of the editing power of the program. As can be seen below, the View and Settings menus offer a similar sized list of options to the Edit menu.
Notepad2 can be downloaded from Flo's Freeware site, although I use a modified version available from PortableApps.com.
