Is there a hot-key to jump between markers in the timeline?

Question

I want to be able to cycle through the frames I set markers on (I have cameras bound to each marker so these are usually the first frame in a shot). Is there a hot-key for this?

Answer 1

Jumping between markers has now been included in trunk as of r60881 with CtrlShift+←/→ (left/right arrows)

Answer 2

While @gandalf3's solution worked, I found it a little awkward to set up (user preferences that rely on scripts that need to be in your project, if I understood correctly), and I found that there's now a built-in shortcut adding feature on the menu:

• In the timeline viewport menu, click Marker
• Right-click on "Jump to Previous Marker"
• Click on "Add Shortcut"
• Hover over the pop-up "A" box, so that it turns into "Press a Key"
• Hit your target combination, eg "Alt-Left"
• (repeat for "Jump to Next")

I might be missing something the scripts in @gandalf3's answer provide, please let me know if so!

Answer 3

AFAIK, there is currently no shortcut in 2.68 to do this. (there was in 2.4x) However, you can create your own operator to do this using blenders python API:

I am not very experienced in python, but I came up with two scripts for jumping to the next and previous markers: (pardon my bad python)

Jump_to_next.py:

import bpy
#jump to next marker

class MoveOperator(bpy.types.Operator):  
    bl_idname = "marker.jump_to_next"  
    bl_label = "Jump to next marker" 

    def execute(self, context):  
        frm=0
        frm_close=0
        frm_first = bpy.context.scene.frame_end
        def switchcam():
            if markname:
                if camname != markname:
                    for area in bpy.context.screen.areas:
                        if area.type == 'VIEW_3D':
                            for space in area.spaces:
                                if space.type == 'VIEW_3D':
                                    if space.region_3d.view_perspective == 'CAMERA':
                                        override = {'window': bpy.context.window, 'screen': bpy.context.screen, 'area': area, 'scene': bpy.context.scene, 'region': bpy.context.region, 'space': space}
                                        bpy.ops.view3d.viewnumpad(override, type='CAMERA')
                                        bpy.ops.view3d.viewnumpad(override, type='CAMERA')
                                    else:
                                        print ("not in camera view")
                                else:
                                    print ("space is not a 3D view")
                        else:
                            print ("area is not a VIEW_3D")
                else:
                    print ("camera bound to next marker is already active")
            else:
                print ("marker is not bound to a camera")

        # get some vars:
        now = bpy.context.scene.frame_current
        cam = bpy.context.scene.camera
        if cam:
            camname = cam.name
        frm_close = bpy.context.scene.frame_end

        # Loop through markers and test how close to the current frame they are:

                    markname = TimelineMarker.camera
                    if markname:
                        markname = TimelineMarker.camera.name
            if frm < frm_first:
                frm_first = frm
        #Test if there is a marker that met requirements:
        if frm_close != bpy.context.scene.frame_end:
            #set scene frame to the frame of closest marker:
            bpy.context.scene.frame_set(frm_close)
            switchcam()
        else:

            else:

You can make these into shortcuts by

1. Paste into the text editor and check the Register option in the header:

   

2. In User Preferences (CtrlAltU)> Input, scroll down to the context you want to use the shortcut in (e.g. Timeline), expand it and click Add new.

3. Type in the operator name (marker.jump_to_next or marker.jump_to_prev) and set the shortcut to whatever you want (e.g. Page Up):

   

4. Save the default .blend. (CtrlU) This is necessary to save the python script so the operator marker.jump_to_next exists. Be careful when saving the default .blend, this will save information such as geometry, screen layout, User preferences, etc.

Note that you will have to do steps 1-3 twice, once for each operator. (jump_to_next and jump_to_prev)
