FreeMind is a Java-based mind-mapping application that stores maps as a XML dialect and can also run as an applet:
Standard Mac OS X keybindings
If, like me, you absolutely loathe the default key bindings (which use Ctrl instead of Command), find your user.properties file (it is in the freemind folder, inside your home directory - a major Mac OS X no-no that I'll let pass for now) and change the Keystrokes section to look like this:
## {{{ Keystrokes ## ## These are the accelerators for the menu items. Valid modifiers are: ## shift | control | alt | meta | button1 | button2 | button3 ## Valid keys should be all that are defined in java.awt.event.KeyEvent ## (without the "VK_" prefix), but I found this buggy. All normal char's should work. # ## The standard keybindings use control instead of command - which is ## unspeakably evil for Mac users, so here's an alternative: # ##Commands for the program keystroke_newMap = meta N keystroke_open = meta O keystroke_save = meta S keystroke_saveAs = meta A keystroke_print = meta P keystroke_close = meta W keystroke_quit = meta Q keystroke_export_to_html = meta E keystroke_export_branch_to_html = meta H keystroke_open_first_in_history = meta shift W keystroke_previousMap = meta LEFT keystroke_nextMap = meta RIGHT keystroke_mode_MindMap = alt 1 keystroke_mode_Browse = alt 2 keystroke_mode_File = alt 3 keystroke_node_toggle_italic = meta I keystroke_node_toggle_boldface = meta B keystroke_node_toggle_underlined = meta U keystroke_node_toggle_cloud = meta shift B keystroke_undo = meta Z keystroke_redo = meta Y keystroke_delete_child = DELETE ##Node editing commands keystroke_cut = meta X keystroke_copy = meta C keystroke_copy_single = meta shift C keystroke_paste = meta V keystroke_remove = none keystroke_add_arrow_link_action=meta L keystroke_add_local_link_action=meta shift L ## Unline with control X, the node you remove with action remove cannot be ## pasted again.
