Opening and Launching
Opening a file
If you double-click a text file (a file with the extension ".txt"), 4Pane tries to open it in your chosen text editor. When 4Pane first starts,
it searches your system for the standard ones, kwrite and gedit, so this should work "out of the box".
If it doesn't, or if you want to change things, it can be configured using the "Open With..." dialog.
4Pane should similarly be able to open other common types of file e.g. pdf files, images. If you try to open a file that it doesn't recognise,
the "Open With..." dialog will automatically open.
Another way to open a file is from the context menu, and this is useful if there is more than one application available to open
a particular type of file. If you right-click such a file, one of the items in the resulting context menu will be "Open with...". Selecting
this produces a submenu containing the known applications appropriate to the file; beneath these will be the option "Other" which again
leads to the "Open With..." dialog.
If you bring up a context menu for a file that 4Pane doesn't know how to open, it will still contain "Open with...", but this time not as a
submenu. Selecting it will once again produce the "Open With..." dialog.
Launching an Executable file
An executable file is an application or a script that your computer can run. If you double-click such a file in 4Pane it will be launched (assuming that you
have the right permissions etc).
However you might sometimes want an executable script to be opened in an editor instead of running. The easiest way to do so is to drag it onto
an Editor icon, but an alternative is to double-click the file while pressing the Ctrl key. 4Pane will then treat it
as though it were not executable, and try to open it.
