Linux: The Ultimate Guide

Folder Mode: You can directly search for commands and run them 
when Enter is pressed.
2. 
Extended Mode: You can search for applications installed on your 
system and view command history.
To switch between modes, you can click the Up or Down arrow keys
when the entry is fixed or click the arrow on the right-hand side of the 
input.
Collapsed Run Mode
The Folder View Finder shows only search entries, selected program 
icons, close buttons, and then Launch. As you type entries, it will search 
for available applications, command history, and custom actions, showing 
the same potential in the pop-up menu. If one match is found, it will be 
automatically terminated at login.

introduced.
xfconf – Storage System
Xfconf is a consecutive setup system (similar to a tree) in which baby 
nodes are close to the root called “channels.” All settings under channel 
nodes are called “properties.”
Valid channel names and locations are made up of uppercase letters 
ASCII US-English A–Z, lowercase letters a–z, numbers 0–9, dash (–), and 
underscore (_). No other characters are allowed in channel names. Letters 
less than (()) and larger than (()) (also called “angle brackets”) are also 
allowed in property names but not in channel names.
Property names refer to the “full route” under its channel, for example: 
“/main/history-window/last-accessed.” Of course, when inquiring about a 
particular property, the channel should be specified separately.
xfce4-dev-tools – Development Tools
These tools are a collection of tools and tools for xfce developers and 
people who want to build xfce from Git. Additionally, it contains an xfce 
developer handbook.
XFCE CI TEMPLATES
[CI Folder] (ci /) contains a build _project . yml template for building vari-
ous xfce projects, as well as supporting documents such as “build _libs . 
sh,” which handles building any dependencies needed. It helps us to avoid 
repeating the same building code for each project.
Exo – Assistant Applications
Exo is an expandable library used on the xfce desktop, first developed by 
oscillation. It has auxiliary applications utilized throughout the xfce desk-
top to manage selected applications and edit .desktop files. Exo is focused 
on application development and is considered suitable for use in produc-
tion. You no longer need to define the previous EXO_API_SUBJECT_
TO_CHANGE logo.
