"Geany is a powerful, stable and lightweight programmer's text editor that provides tons of useful features without bogging down your workflow." (https://www.geany.org/)

The local Geany manual is locally availabe.

In the next section are the instructions for installing geany along with several of it's optional plugins.

Once those plugins are installed you will find many useful capabilities in geany. For example;

• granual control of the layout and rendering
• insert the current datetime
• search, including regex
• set and jump back to marked lines
• removing trailing spaces
• visually select HTML color codes
• export as HTML
• column selection
• sort lines
• deduplicate lines
• insert Unicode characters
• spellcheck
• multi-pane display

As with installing most software, you will use the 'apt' program with sudo rights. If you are running Kali from a live USB you may not need to use the sudo program.

In the following example, run the first three lines one at a time. That will update your current system, and install geany. Note that whenever you install new software, be sure to first run the first two commands shown below.

After the first three have run properly, you can run the 4th which install several pieces of software at one.

Launch geany by clicking on it's icon. You might want to copy that icon to both the 'panel' and 'favorites'.

The illustration below will be used to point-out the key point of the program. Click on the image to expand or contract it.

• The top command menu drops down to show the actions you can take
• The top icon bar is a shortcut for common actions
• The tab bar shows each file that is open for editing
• The left side-bar can display with symbols or the open documents
• The center panel is the current document being edited. To the left are the line numbers, and indicators of long lines, along with a blank area just to the right of the line number. In that blank area you can single click to mark that line and return to it later. Another click will remove the mark.
• The small squares to the left of the document contents has either a '+' or '-' symbol. Clicking these will toggle between collapse and expand that code block.
• The thin vertical line in the document body show the 72 character mark. This is useful for seeing how text will wrap in different situations.
• The side-bar on the right provides an icon view of the document's contents. By clicking in that area you can instantly 'scroll' to that section and see it highlighted.

• At the bottom right is a selection control. Usually this is kept on 'status'. Click the up and down arrows to see the options. This shows several options for what to display in the area to it's right.
• At the very bottom is the status line.
