Some [wiki:Shortcuts default hotkeys] may surprise editors from iD and Poltrach. All shortcuts will be present under [Help/Preferences/Shortcuts "Hotkeys" tab in F12 menu] you can adjust and fine-tune them or reset at any moment. * [wiki:Help/Preferences Preferences] - some of the settings [Help/Preferences/Advanced#Explanation are not acceptable via settings menu] or just spread everywhere in the editor * [wiki:Help/Action/Upload Upload changeset] - explains why you create a '''changeset''' and low level details when you upload data to the OSM server == Workflow examples == * [[Help/Downloading data]] - there many ways to load existing data in JOSM * [wiki:Help/AudioMapping Audio mapping:] playing voice notes and synchronizing them with your GPS tracks in JOSM * [wiki:Help/Preferences/Validator Validator messages] - will explain how to fix common mistakes and what do they mean {{{ #!html }}} == JOSM tools == Search among all JOSM tools and menu items - Ctrl+Spacebar Selection (displayed in [wiki:/Help/Dialog/SelectionList Selection Dialog]): * [Help/Action/Select#Selecttool Select] (S) - contain many modifiers, including [Help/Action/LassoMode lasso mode] * [Help/Action/Search Search] (Ctrl+F) - a very powerful tool and a query language with [wiki:Help/Action/Search#Keywords over 28 keywords] and flexible operators to combine them in flexible manner. Not to mention regex and mapcss filters. * (Shift+F3) - search objects by preset * [[Help/Plugin/UtilsPlugin2#Selection]] * [Help/Action/SelectNonBranchingWaySequences Select non branching way sequences] (Shift+W) - useful when editing highways, railways, rivers, power networks and networks in general * [Help/Action/SelectAll Select all] (CTRL+A) is more useful after you download precise list of objects Tags (displayed in [wiki:Help/Dialog/TagsMembership Tags/Memberships Dialog]): * [Help/Action/Copy Copy] (Ctrl+C) - copy selected objects to the buffer * [Help/Action/PasteTags PasteTags] (Ctrl+Shift+V) - paste previously copied tags * Tabular editor (Ctrl+T) from ([[Help/Plugin/UtilsPlugin2]]) * [Help/Action/Duplicate Duplicate] (Ctrl+D) not only tags but also their geometries * (Shift+R) (from [[Help/Plugin/UtilsPlugin2]]) copy tags from previous selection * Standard [Help/Dialog/AddValue Add value] (Alt+A) dialogue provides 5 shortcuts to 5 last used tags without closing this dialogue Topology tools and changes: * [Help/Action/MergeNodes Merge] (M) two or more points * [Help/Action/UnGlue UnGlue] (G, opposite of above) explode single point into multiple * [Help/Action/JoinNodeWay Join point into a way segment] (J) * [Help/Action/DisconnectNodeWay DisconnectNodeWay] (Alt+J, opposite of above) disconnect a node from a way segment * [Help/Action/AddIntersections AddIntersections] (Shift+I) (from [[Help/Plugin/UtilsPlugin2]]) - will create nodes at places where current selections intersects (or self intersects) * [Help/Action/SplitObject Split geometry by selected line] (Alt+X) (from [[Help/Plugin/UtilsPlugin2]]) * [Help/Action/SplitWay Split way] (P) - split way by a node * [Help/Action/CombineWay Combine Way] (С) - combine several selected ways in one * [Help/Action/JoinAreas Join overlapping areas] (Shift+J) Geometry tools (precision in angles): * [Help/Action/Draw#Anglesnapping Anglesnapping] (A, twice) will ease drawing way segments in 30°, 45°, 60° and 90° degrees * [Help/Action/Extrude#Basicusage Extrude] (X, with modifiers) tool will ease drawing of strictly perpendicular segments Geometry tools (alignment): * [Help/Action/AlignInLine Align in line] (L) will align selected nodes into a line * [Help/Action/DistributeNodes Distribute] (Shift+B) as above, but also place them at equal distances * [Help/Action/Parallel Parallel] (Shift+P), draw lines and curves parallel to each other, draw nested infrastructure quickly Viewport control: * Explained at [Help/MapView MapView], [Help/Menu/View "View" menu] and [Help/Action/Zoom Zoom tool] * [Help/Action/JumpToPosition JumpToPosition] == JOSM interface == {{{ #!html }}} || [[Image(9229-en.png, 300px)]] || [[Image(9229-en-expert-false-Moscow Kremlin.png, 300px)]] || [[Image(9229-en-expert-true-Moscow Kremlin.png, 300px)]] || [[Image(9229-en-expert-true-Moscow Kremlin-terminology.png, 300px)]] || || Starting screen may be confusing for newcomers, you need to get data first using [Help/Action/Download Download menu] || Here is what you will see if you choose Moscow Kremlin || Additional and more complex tools may be activated with [Help/ExpertMode Expert mode] (pay attention to the left side of the screen) || [[wiki:JOSM interface]]: 1 - '''[[wiki:JOSM interface|main menu]]''', 2 - [Help/MainToolbar main toolbar], 3 - [Help/EditToolbar edit toolbar], 4 - [Help/StatusBar status bar], 5 - ..., 6 - '''[Help/ToggleDialogs toggle dialogs]''', 7 - Search menu items, 8 - [Help/MapView map view].
