The IMAGE_SEL menu block items define the key "display" which is used in subsequent image commands via the menu block "IMAGE_DO" (image_do.html) and set color commands via the menu blocks "IMAGE_COL" (image_col.html) and "IMAGE_COL2 (image_col2.html).
The "ACT_" items actually share the menu block NICE_SEL macros (nice_sel.html) for key "active manipulation.
The IMAGE_SEL menu block is loaded with the file MAIN_CMDS:load_image_sel.com.
All atom sfrom the current "WORK_SEGM" are assigned to the key "display".
Copies the contents of the key "active" to the key "display" (MAIN_CMDS:image_use_active.cmds). MAIN_CMDS:image_use_work.cmds
Copies the contents of the key "active" to the key "display" (MAIN_CMDS:image_use_active.cmds).
Defines the whole history list (all clicked atoms) to the key "display" (MAIN_CMDS:image_use_history.cmds).
Removes hydrogen atoms from the key "display".
Redefines the key "display" by selecting all residues with the same residue name as all clicked atoms being part of the history list (MAIN_CMDS:image_use_by_res_name.cmds).
Redefines the key "display" by selecting each tenth CA or P atom for proteins and nucleic acids respectively (MAIN_CMDS:image_use_each_ten.cmds).
Selects the atoms of the last clicked molecule (MAIN_CMDS:sel_active_segm.cmds).
Selects the residues between the last two clicked atoms (MAIN_CMDS:sel_active_2res_rang.cmds). Residues do not need to be a part of the same molecule or segment.
Select atoms within a certain number of covalent bond steps from the last clicked atom (MAIN_CMDS:sel_active_neigh.cmds).
Switches between the ADD_MODE ON (MAIN_CMDS:sel_add_mode_on.cmds) and OFF (MAIN_CMDS:sel_add_mode_on.cmds).
