  • reintegrates 'help' into 'trunk'
    • tweak arb documentation:
      • automatically link
        • ticket references to arb bug tracker (only affects html version).
        • found URLs.
      • page titles
        • warn about long titles.
        • introduce SUBTITLEs (automatically triggered by multi-line titles in source files).
        • increase allowed length (limited by subwindow width).
      • cleanup header sections in all helpfiles.
      • fix and/or update several help files.
      • document syntax of help sources.
      • build issues:
        • when xml validation fails, next build no longer uses invalid xml ⇒ keeps failing.
        • remove output files on error (including files below ARBHOME/lib).
        • pipe output through logs to ensure proper wrapping in Entering/Leaving lines.
    • moves Tree admin + NDS menu entries to top of menu
  • adds: log:branches/help@18783:19531
  • Property svn:eol-style set to native
  • Property svn:keywords set to Author Date Id Revision

11TITLE           Tree display keyboard reference
12
13OCCURRENCE      Focus tree display area and press one of the hotkeys described below.
14
15DESCRIPTION     List of keys recognized by ARB_NTREE tree display
16
17SECTION         Marking species and folding groups
18
19                    Key   Description
20                   ==========================================
21                    m     mark/unmark (sub-)tree
22                    i     invert marks of (sub-)tree
23                    x     expand (Marked->Unmarked->All)
24                    c     collapse (Terminal->All)
25
26                  If you point to a subtree with the mouse while pressing one of these keys, the action is
27                  performed on the subtree. Otherwise (if you point somewhere outside of the tree)
28                  the whole tree is targeted.
29
30                  If you press < SHIFT + Key > the function works on the opposite set:
31
32                     - Instead of the subtree, the rest of the tree is targeted.
33                     - Instead of the whole tree, all species NOT in tree are targeted.
34
35                  If you press < CTRL + Key > the function works on ALL species (if it makes sense).
36
37                  SPACE toggles the mark(s) of the LINK{selected.hlp} or group.
38
39                  RETURN toggles the folding of the selected group.

42SECTION         Selecting species
43
44                    Key              Description
45                   ===============================================
46                    Cursor up/down   select previous/next species
47                    Home/End         select first/last species
48
49                  If you press < CTRL + Key > these function only select marked species
50                  and if the selected species is inside a folded subtree all parent groups
51                  will be unfolded temporarily (to make the species visible).
52
53                  If you press < SHIFT + Key > folded groups will temporarily unfolded and traversed,
54                  without SHIFT folded groups will be skipped.

57SECTION         Selecting groups
58
59                    Key                       Description
60                   ===============================================================================
61                    ALT + Cursor up/down      select previous/next group (inside enclosing group)
62                    ALT + Home/End            select first/last group    (inside enclosing group)
63                    ALT + Cursor left/right   ascend/descend out-of/into groups
64
65                  Terminal groups will unfold when trying to descend further.
66
67SECTION         Howto switch selection between groups and species
68
69                * when a group is selected, you can use SHIFT + Cursor down/up to
70                  select the first/last species of that group.
71                * when a species is selected, you can use ALT + Cursor left/right to
72                  select the enclosing group.
73
74NOTES           Expanding/collapsing is implemented in such way, that some key-combinations lead to
75                determined tree-displays.
76
77                Examples:
78
79                  Key-Combo   similar to
80                 =================================================
81                  cc          group all
82                  ccx         group all except marked
83                  xxx         ungroup all
84                  xxxc        group terminal groups
85
86                If a subtree does not contain unfolded groups the collapse keys target the first
87                parent group instead.
