Context help can be requested from almost any \CGG{} window or subwindow by pointing with the mouse cursor on the GUI element of interest and pressing \texttt{Alt/h}. That HTML manual page will be shown via the configured web browser, which is assumed as most relevant to the GUI element currently under the mouse pointer.

+\subsection{How Context Help works}%
\label{sub:how_it_works}
The hotkey to request context help is \texttt{Alt/h}. What particular help page is shown, depends on the mouse cursor location while \texttt{Alt/h} is pressed. Usually, when the mouse is located in some window or dialog, the help page related to the functionality of this window or dialog is shown. In this case the mouse can point either on some widget, or on an empty area in the window. In \CGG{} GUI there are several rich loaded windows, \textit{Timeline} and \textit{Compositor} for example. In such a case different help pages can be requested depending on the particular GUI element under the mouse. For example, pressing \texttt{Alt/h} while pointing on the \textit{Autos curve} in a track would show help on \textit{automation keyframes} section, pointing on the \textit{Overlay} mode button in the \textit{patchbay} would show help on \textit{overlays}, pointing on the \textit{camera control} in \textit{Compositor} would show help on \textit{camera and projector}.
\item If the rate at which frames are captured during Recording is much lower than the framerate of the source, the video will accumulate in the recording buffers over time and the audio and video will become out of sync. Decrease the number of frames to buffer in the device in \texttt{Settings $\rightarrow $ Preferences, Recording} tab so that the excess frames are dropped instead of buffered.
\item If loading files locks up, this might be because \CGG{} is building picons/vicons for the Resources window. If you load a large number of images it needs to decompress every single image to build a picon/vicon. Go into \texttt{Settings $\rightarrow$ Preferences, Appearance} tab and disable \textit{Use thumbnails in resource window} to skip this process. Keep in mind though, that it only has to create these thumbnails the first time a new piece of media is loaded or the values are changed.
\item For an older computer with less CPU power, in \texttt{Settings $\rightarrow$ Preferences, Appearance} tab, be sure that \textit{Autocolor assets }is disabled; set \textit{View thumbnail size} \& \textit{Vicon quality}\& \textit{Vicon color mode} to lower values or switch to \textit{No Play} instead of \textit{Full Play} in the Resources window (this is to the right of the word \textit{Visibility} in the left hand side of that window). You will then have more CPU and more memory available to do actual editing.
+ \item If you have updated your Operating System or newly installed some applications, it is
+possible that your LV2 plugin path may have been modified and be in disagreement with what you have set
+for \CGG{}. This could result in a crash upon startup. Look at the messages in the window from where
+you started \CGG{} to see if they look similiar to the following:
+\begin{lstlisting}[numbers=none,xleftmargin=10mm]
+LOAD: http://eq10q.sourceforge.net/matrix\_lr2ms
+LOAD: http://eq10q.sourceforge.net/matrix\_ms2lr
+LOAD: https://community.ardour.org/node/7596
+LOAD: urna-comp
+** segv at 0x7f2cd80813c4 in pid 4540, tid 4540
+\end{lstlisting}
+The last line before the \textit{segv} indicates the name of the LV2 plugin that is causing problems.
+Please refer to the section on LV2 plugins \ref{sec:audio_lv2_calf_plugins} to resolve the issue.
+ \item Sometimes there is a problem creating a new report issue in the Mantis Bugtracker
+using chrome and you lose what you just typed in. Generally when logging into the bugtracker, the
+option "only allow with this IP address" needs to be disabled, then the bug tracker will work fine.

\textbf{Some Helpful User Readable Text Dumps}
This usually indicates that you are out of Operating System file descriptors. You can increase the amount easily with the following command line: \texttt{ulimit -n 4096} where 4096 is a size suggestion but can be increased. You can include this command line in your \texttt{.bashrc} or \texttt{.profile} file for the user login which gets run every time you login, or modify the Operating System limit for everyone in the system file, which for Fedora is \texttt{/etc/security/limits.conf}. Alternatively, you can reduce the number of file descriptors needed by going into \texttt{Settings $\rightarrow$ Preferences, Appearance} tab and unchecking the flag \textit{use thumbnails in resource window}.

+\textit{Using a non-supported locale could cause a failure in starting \CGG{} with the following error.}
+
+\begin{lstlisting}[numbers=none,xleftmargin=10mm]
+
+ BC_WindowBase::init_im: Could not open input method.
+ unjoined tids / owner 1
+ 00007f543dffb700 / 00007f54989d5840 12BC_Clipboard
+
+\end{lstlisting}
+
+This is caused by LC\_CTYPE setting you are using, and maybe other Locale settings too.
+For example, using the following will cause the \textit{unjoined tids} error.
+
+\begin{lstlisting}[numbers=none,xleftmargin=10mm]
+ LC_CTYPE="en_IL" /mnt0/build5/cinelerra-5.1/bin/cin # set LC_CTYPE and start cin
+\end{lstlisting}
+
+This is an operating system error which is resolved by using the following startup instead:
+
+\begin{lstlisting}[numbers=none,xleftmargin=10mm]
+
+ LC_CTYPE="en_GB.utf8" /mnt0/build5/cinelerra-5.1/bin/cin # set LC_CTYPE and start cin
+\end{lstlisting}
+
+You can either export the LC\_CTYPE variable before starting \CGG{} or
+add this in your bash startup file or simply run from the command line as shown above.
