The dialog for loading files can be brought up by pressing ALT + L, clicking the folder icon in the toolbar or selecting the corresponding item from the File menu.
An animation always consists of at least two frames. To select multiple files in the file open dialog, you have three options (standard semantics for file choosers):
- Hold the SHIFT key while selecting filenames, using the mouse. This will only select the files chosen.* Hold the CTRL key while selecting two filenames, using the mouse. This will select all the files between the selected two.
- Click into the file list to activate it and press CTRL + A, This will select all files in the directory.
You may combine these actions. For example, you might want to select all files in a directory first, using CTRL+A and afterwards de-select individual ones.
After the desired files are highlighted, click the "open" button.
